What is the difference between Tiny II and III?

All is OK, this is only the firmware update.
Because Trace II/III/IV use the same firmware, so we change OSD Text as 'Trace IV' in firmware V2.8,
LED status in V2.8:
Power on: LED(blue) blink
GPS locked: LED(red) solid, No blue

What is the difference between II and III?

The Tiny II and III have the same OSD board, the Tiny III just update the GPS to 10Hz, the current sensor of Tiny III is smaller than the one of Tiny II

Trace OSD inludes a PSU unit(Power Supply Unit) in Current sensor module, it can supply 5V/12V power for camera/VTX

Trace OSD inludea the AAT decode unit, it can work with Skylark AAT directly

 

Tiny OSD is not PSU

If Tiny OSD need connect with AAT conver module before it work with Skylark AAT.

This GPS sensor (using the 4hz) is much more accurate the faster you are moving. It was VERY (or at least seemed more realistic) today while flying the new Radian. My full throttle climbing speed is 45 mph and the altitude caught up very quickly and the speed changes responded much faster.

Skylark 5.8G TX/RX

We found that most problems come from RTX or antenna.
The RTX or antenna include magnetic material.
So we will release two new RTX(2.4G RTX and 5.8GRTX, with planar antenna) for AAT.
They use all-aluminum body and can be compatible with most of VTX.
I will update some pictures for reference

Skylark AAT

Skylark AAT Suite is aimed for FPV enthusiasts. It includes a Auto Antenna Tracker unit and a Trace OSD unit

Features
Easy to install and easy to use
PAL/NTSC compatible
60A current sensor
RSSI Auto detected | Auto "Setting Home"
With barometer
Free firmware upgrade

Tracks 360º horizontally and 90º vertically
Auto Antenna Tracker includes compass
Open API | Support secondary development

Basic principle
When the Trace OSD powers on, if GPS get over 4 satellite signals, OSD will save the position as HOME point.
The Trace OSD calculates the angles that the AAT should rotate, according to the current position and HOME point.
The Trace OSD send the angle information to Skylark AAT via Audio channel of TX..
The AAT(Auto Antenna Tracker) only receives the angle information and doesn't record data.

Recommended procedures
1. Keep the OSD closing your AAT
2. Power on Trace OSD or Reset Trace OSD, and get the HOME point.
3. Check the AAT orange light is blinking.
4. Start Flying
