Pi In the Sky is a simple and reliable GPS radio tracker board for the Pi.
Together with the supplied, open-source software it embodies the experience of about 40 successful flights, nearly half of which have used the Raspberry Pi.
It features:
Efficient built-in power regulator providing run time of over 20 hours from 4 AA cells
Highly sensitive UBlox GPS receiver approved for altitudes up to 50km
Temperature compensated, frequency agile, 434MHz radio transmitter
Temperature sensor
Battery voltage monitoring
Sockets for external i2c devices, analog input, external temperature sensor
Allows use of Raspbery Pi camera
Mounting holes and spacers for a solid connection to the Pi
The open-source software provides these features:
Radio telemetry with GPS and sensor data using UKHAS standard
Radio image download using SSDV standard
Multi-threaded to maximize use of the radio bandwidth
Variable image size according to altitude
Stores full-definition images as well as smaller transmitted images
Automatically chooses better images for download
Configurable via text file in the Windows-visible partition of the SD card
Supplied as github repository with instructions, or SD card image
