Configurazione GeoLink

1 Supporto GeoLink

GeoLink è supportato dalla versione firmware 2.5. Per utilizzare tutte le funzioni è necessario abilitare il supporto nelle Impostazioni Spirito - prima scheda Generale General tab. Dopo l'abilitazione, salvare le impostazioni e alimentare nuovamente il modello.

2 Calibrazione della bussola

Tutti i moduli GeoLink sono stati completamente testati e calibrati. L'unica cosa di cui il pilota potrebbe aver bisogno è ricalibrare la bussola. La bussola è fondamentale per determinare la direzione del modello per una corretta navigazione nello spazio. La bussola rileva il campo magnetico terrestre (campo geomagnetico) e in questo modo può determinare la direzione in qualsiasi momento. Purtroppo il campo geomagnetico è diverso ovunque. Pertanto se il modello verrà utilizzato al di fuori della Repubblica Ceca, si consiglia vivamente di eseguire una nuova calibrazione. I moduli GeoLink sono calibrati in fabbrica per la Repubblica Ceca.

2.1 Come controllare

Per verificare che GeoLink sia calibrato correttamente per la tua area, avvia le Spirit Settings e apri la finestra GeoLink settings. Nella scheda Informazioni Info tab puoi vedere il valore corrente dell'intestazione.

Posizionare il modello o solo GeoLink al Nord il più vicino possibile, in modo che la direzione di volo del modello sia davanti alla freccia. Idealmente confronta con una bussola analogica.

IMPORTANTE: Assicurarsi che durante la lettura del titolo, il modello sia sul piano orizzontale. In modo che nella scheda Modulo Module tab vedrai un'inclinazione di 0 °. Poiché alcuni modelli come SAB Goblin, MSH Protos sono inclinati, è necessario prima trovare l'inclinazione zero del modello.

Quando ci si dirige verso Nord, si dovrebbero vedere circa 90 +/- 4 ° . Il valore misurato non dovrebbe essere lontano da questo.

Si consiglia di non utilizzare dispositivi intelligenti per il confronto della direzione della bussola. Questi di solito non sono calibrati affatto né consentono la calibrazione. Una bussola analogica è la migliore per il confronto.

2.2 Comportamento strano

Se la calibrazione della bussola è sbagliata, noterai che funzioni come Geo-fence, Return to Home, Position Hold non funzionano esattamente. Ad esempio, quando Return to Home è attivato e il modello ha raggiunto la posizione Home programmata, il modello potrebbe muoversi in modo circolare attorno a quel punto, invece di rimanere stabile. Più grande è il cerchio, maggiore è l'errore di direzione della bussola. Se riesci a osservare sempre questo comportamento, allora è un chiaro segno che devi ricalibrare la bussola.

2.3 Processo di calibrazione

Per eseguire la calibrazione è necessario entrare in Impostazioni Spirito / GeoLink / Modulo e fare clic sul pulsante Calibration request. Ora puoi scollegare l'alimentazione e il cavo di interfaccia USB dal modello.

1. Alla successiva accensione del modello si noteranno immediatamente 3 serie di lampeggi rapidi del LED sul GeoLink.
2. Il LED di stato indicherà quindi l'avanzamento della calibrazione. Inizia a muoverti con il modello in tutte le direzioni e angoli possibili per imitare una sfera. Qualsiasi lampeggio del LED indicherà che sono stati acquisiti nuovi dati di calibrazione.
3. Ruota con il modulo finché non vedrai lampeggiare periodicamente il LED. A questo punto la calibrazione è terminata. Dopo la successiva alimentazione, il modulo è pronto per il funzionamento.
   

Per gli elicotteri di classe 600 e piu grandi si consiglia di eseguire la calibrazione mentre GeoLink non è montato. In questo modo può essere più comodo e più facile.
La calibrazione dovrebbe essere eseguita idealmente sul campo di volo, ma di solito può essere eseguita anche al coperto se il segnale e' buono.

Calibration will not finish until it is fully done. If power is turned off while calibration is not finished, the calibration process will start from the beginning on next power up.

3 Come configurare

Come primo passo, il pilota deve decidere quale funzione GeoLink desidera utilizzare. Per scoprire come funziona ciascuna funzionalità, visita la Pagina delle caratteristiche. Il pilota può abilitare più funzionalità contemporaneamente, se necessario.

Seleziona la funzione che desideri utilizzare nella scheda Aiuto della finestra GeoLink. Dopo l'abilitazione, saranno accessibili i parametri disponibili per la particolare funzione. Con questi parametri il comportamento della caratteristica selezionata può essere personalizzato per soddisfare le esigenze. Per i primi tentativi si consiglia di utilizzare valori predefiniti.

3.1 Attivazione

Puoi verificare se il meccanismo di attivazione funziona correttamente anche prima del volo effettivo controllando la scheda Aiuto. Se una funzione è attiva, vedrai ACTIVE o in altri casi INACTIVE.

IMPORTANTE Per motivi di sicurezza, non attivare alcuna funzione GeoLink prima che il modello sia in aria ad un'altitudine appropriata.

3.1.1 Funzione Stabi

By default all GeoLink features are engaged as soon as a Stabi function is active. For example if Coaxial or Rescue mode is engaged the GeoLink feature is engaged as well and complement operation of a Stabi function by acting simultaneously. We recommend to set Stabi/Function to Coaxial mode for Geo-fence, Return to Home and Position Hold features.

3.1.2 Dedicated GeoLink channel

Alternatively you can assign a GeoLink feature to any free channel in the General/Channels window. In the right part of the Spirit Settings software select which feature you would like to assign. (for example F: Return to Home). Then select appropriate channel which will be used for engaging. You can use same channel for multiple features at the same time.

4 Geo-fence

To enable this feature it is required to tick the CheckBox in the GeoLink window/Aid tab.

4.1 Usage

The feature can be engaged at any given time by a command from your radio. It is important to decide in which way the feature can be engaged as there are two options.

1. To engage with Stabi function - in this case the feature is engaged when programmed Stabi function is engaged. This mean you do not need to assign any other switch than when used for e.g. Stabilisation mode
2. To engage with assigned GeoLink channel - it is required to assign F: GeoLink Geo-fence function in the General/Channels to an available channel.

Please make sure that Geo-fence Area was defined.

4.2 Modes

If Geo-fence is engaged by assigned GeoLink channel there is possibility to use tri-state switch also for programming of a new Geo-fence area. In the Channels window you will be able to see Function as On (1), Off and On (2) which is corresponding to 100%, 0% and -100% channel value.

When On (1) is displayed it mean that at this point Geo-fence is engaged and flight area is restricted. The model will return upon exceeding the area to the center of the area. Then pilot has to re-engage the feature in order to continue in flight.

When On (2) is displayed the unit is in a programming mode which allow to overwrite current Geo-fence to the new with position at which the model currently is. Please note that it will not work if model is flying or if GNSS signal is very weak.

4.3 New Geo-fence programming

It is possible to program the Geo-fence either with the Spirit Settings by selecting a points at the Map. Or there is possibility to use GeoLink channel to do so even if you are out of a computer.

If assigned GeoLink channel is used you have to set On (2) function state and keep it on for at least 2 seconds. At this period Status LED of the unit will turn off and after 2 seconds new Geo-fence point is programmed. Pilot has to define two points that will determine new area diagonally. To program both points pilot have to engage the programming two times. From two diagonal points a rectangular area is calculated. After the first point programming the Status LED at the Spirit will be still Off. After the second point programming the LED must turn On which will signalize success. New area is applied immediately.

5 Altitude Limit

To enable this feature it is required to tick the CheckBox in the GeoLink window/Aid tab.

5.1 Usage

The feature can be engaged at any given time by a command from your radio. It is important to decide in which way the feature can be engaged as there are two options.

1. To engage with Stabi function - in this case the feature is engaged when programmed Stabi function is engaged. This mean you do not need to assign any other switch than when used for e.g. Stabilisation mode
2. To engage with assigned GeoLink channel - it is required to assign F: GeoLink Altitude Limit function in the General/Channels to an available channel.

5.1.1 Triggering Acceleration

This parameter is key for engaging the Rescue mode fast enough if your model is approaching towards the ground. The faster is descending velocity, the faster the Rescue is engaged. This mean that the Rescue can be engaged above configured Minimum limit to save the model safely. If model is approaching the Minimum limit slowly then the rescue is engaged at configured level. Low Triggering Acceleration value is causing only minor difference.

6 Return to Home

To enable this feature it is required to tick the CheckBox in the GeoLink window/Aid tab.

6.1 Usage

The feature can be engaged at any given time by a command from your radio. It is important to decide in which way the feature can be engaged as there are two options.

1. To engage with Stabi function - in this case the feature is engaged when programmed Stabi function is engaged. This mean you do not need to assign any other switch than when used for e.g. Stabilisation mode
2. To engage with assigned GeoLink channel - it is required to assign F: GeoLink Return to Home function in the General/Channels to an available channel.

Please make sure that Home spot was defined in the Map tab.

6.2 Modes

If Return to Home is engaged by assigned GeoLink channel there is possibility to use tri-state switch also for programming of a new Home spot. In the Channels window you will be able to see Function as On (1), Off and On (2) which is corresponding to 100%, 0% and -100% channel value.

When On (1) is displayed it mean that at this point Return to Home is engaged and model will move at the Home spot.

When On (2) is displayed the unit is in a programming mode which allow to overwrite current Home spot to the new with position at which the model currently is. Please note that it will not work if model is flying or if GNSS signal is very weak.

6.3 New Home position

It is possible to program the Home position either with the Spirit Settings by selecting a point at the Map. Or there is possibility to use GeoLink channel to do so even if you are out of a computer.

If assigned GeoLink channel is used you have to set On (2) function state and keep it on for at least 2 seconds. At this period Status LED of the unit will turn off and after 2 seconds new Home position is programmed. Once finished the LED must turn On again.

7 Auto Landing

To enable this feature it is required to tick the CheckBox in the GeoLink window/Aid tab.

7.1 Usage

The feature can be engaged at any given time by a command from your radio. It is important to decide in which way the feature can be engaged as there are two options.

1. To engage with Stabi function - in this case the feature is engaged when programmed Stabi function is engaged. This mean you do not need to assign any other switch than when used for e.g. Stabilisation mode
2. To engage with assigned GeoLink channel - it is required to assign F: GeoLink Auto Landing function in the General/Channels to an available channel.

8 Position Hold

To enable this feature it is required to tick the CheckBox in the GeoLink window/Aid tab.

8.1 Usage

The feature can be engaged at any given time by a command from your radio. It is important to decide in which way the feature can be engaged as there are two options.

1. To engage with Stabi function - in this case the feature is engaged when programmed Stabi function is engaged. This mean you do not need to assign any other switch than when used for e.g. Stabilisation mode
2. To engage with assigned GeoLink channel - it is required to assign F: GeoLink Position Hold function in the General/Channels to an available channel.

9 Altitude Hold

To enable this feature it is required to tick the CheckBox in the GeoLink window/Aid tab.

9.1 Usage

The feature can be engaged at any given time by a command from your radio. It is important to decide in which way the feature can be engaged as there are two options.

1. To engage with Stabi function - in this case the feature is engaged when programmed Stabi function is engaged. This mean you do not need to assign any other switch than when used for e.g. Stabilisation mode
2. To engage with assigned GeoLink channel - it is required to assign F: GeoLink Altitude Hold function in the General/Channels to an available channel.

9.2 Modes

If Altitude Hold is engaged by assigned GeoLink channel there is possibility to use tri-state switch also for disabling Collective Pitch input. In the Channels window you will be able to see Function as On (1), Off and On (2) which is corresponding to 100%, 0% and -100% channel value.

When On (1) is displayed it mean that altitude in which the feature was engaged will be held. Pilot is still able to change Collective Pitch, but in a limited manner. Collective Pitch reaction will be slower than in a normal flight mode.

When On (2) is displayed it mean that altitude in which the feature was engaged will be held. Pilot is unable to change Collective Pitch by pitch stick. So that Collective Pitch steering is fixed and is changed only by GeoLink in order to hold right altitude.

10 Correction Gains

GeoLink features are doing a certain movements to achieve desired position of the model. These movements are small corrections which are dependent on parameters of the model. For very agile models these correction can be smaller. While for heavy and big models you might need bigger in order to reduce time required to achieve desired position.

10.1 Horiontal Gain

Horizontal gain affects features such as Geo-fence, Return To Home and Position Hold. For example if Return to Home feature is engaged and it takes too long to return at programmed home spot it is necessary to increase Horizontal correction. Too high value will result in excess (too visible) corrections even when model is maintaining spot on position.

10.2 Vertical Gain

Vertical gain affects features such as Altitude Limit and Altitude Hold.
