GeoLink offer variety of features that can be enabled on demand while flying. Some can be also combined to offer the experience you would like.

1 TTFF Accelerator

This feature allow to significantly reduce period in which GeoLink module can fix to a navigation satellites. With some devices it takes even few minutes. With GeoLink this period can be reduced to just 6 seconds while no battery backup is needed.

1.1 How it works

When module is powered up for the first time at a given day it is trying to find a satellites. It will do so in a normal way (without any time reduction). With GeoLink this should be between 20 - 35 seconds normally (depending on conditions).

Right after the flight and next power up this period is reduced significantly. When powering up within few minutes to hours you can always notice the time required for Fix is shortened.

Since the module is doing calculations to predict position of the satellites even for the following days, you can feel an improvement even if the module was not running for up to 3 days.

1.2 How can it help me?

If you fly few packs within same day, while time between is less than one hour, then the results are the best. Usually immediately after Spirit unit is initialized you are ready to fly with no additional waiting required.

If you fly just one pack, but each one or two days, you will notice benefits as well.

2 Logging

GeoLink is logging each flight and stores the logs in its memory. It is storing every second while total flight log length can reach up to 1.5 hour. If the memory is exceeded it automatically delete old logs in order to store new one. Logged data are subject to change and could change in the future updates.

2.1 Logging specification

• Up to 1.5 hour
• Up to 63 logged flights
• Recording period: 1 second

2.2 What is being logged?

• Position on Earth: Latitude and Logitude
• Altitude: relative altitude from starting point
• Speed: flying speed of the model
• Heading: direction in which model is flying
• Date and time

2.3 Log viewer

Any logged flight can be viewed on demand with Spirit Settings software. You can see flight paths directly on the map and can re-play the log in a speed you wish.

2.4 Log backup and sharing

Each log can be also backed up or shared with others easily by saving it as file to your computer. The files can be loaded and replayed in the viewer.

3 Return To Home

Whenever you will loose orientation, this function is the best option. You have to only engage the function with your transmitter and wait a moment, until the model returns to defined position.

3.1 Description

Once engaged the model will immediately change its direction to programmed home destination, wherever it is. It can work also upside down, so it does not matter what the orientation is.

All the time the rudder control will still work without any change so that pilot can yaw in any way he wish. The feature will not move with rudder at all, thus pilot will find the model rotated as it was and can change direction at any moment, even when it already returned.

Once model will return it will maintain the position so it can't fly over again.

3.2 With Altitude Hold

This feature can be combined with Altitude Hold.

4 Position Hold

If you are learning the basics this feature can help you significantly in maintaining required spot. If you are not strong in hovering the feature will do the job for you.

4.1 Description

The model is flying similarly as with Coaxial mode. Pilot can control the model fully but all movement speed is controlled so it can't fly too fast. Rather you can fly very safely as with a Coaxial model and without undesired drifting caused by wind. Always when sticks are released the model will stop at that point and will maintain it until other steering command is given. The model can't be flipped over. This feature can work also upside down in the same way.

Rudder control is identical as with a normal flying mode.

4.2 With Altitude Hold

This feature can be combined with Altitude Hold.

5 Geofence

This feature allows to restrict flying area so that when flying over the model will return. Pilot can set a virtual fence in which the model is allowed to fly.

5.1 Description

When model fly over configured fence it will try to stop and return back to allowed area as fast as possible. This feature can work also upside down in the same way. Rudder control is identical as with a normal flying mode.

5.2 With Altitude Hold

This feature can be combined with Altitude Hold.

6 Altitude Hold

If pilot is unable to maintain altitude the feature can control collective pitch automatically for him.

6.1 Description

The model will try to maintain altitude at which the feature was engaged. It can work in a normal flying mode and any Stabi function. Pilot can safely change the altitude by collective pitch movements anytime. If without movement, the altitude is maintained. This feature can work also upside down in the same way.

The feature will not change anything else than collective pitch.

7 Altitude Limit

If you are worried you will forget to engage the Rescue mode in time, this feature is what you are looking for.

7.1 Description

If engaged the model will fly without any change in behavior. But as soon as the model will fly under configured altitude the Rescue mode is activated automatically until the model ascend above this level.

On the other hand if the model exceed configured upper altitude limit it will stop ascending there. The model will maintain the level and pilot can descend on will with collective pitch.
