This project provides hardware and software to create a Data-Acquisition and Presentation System for Gliders including data output to Flight Management Systems like XCsoar.
The core component is a INS-augmented satellite variometer.
The Larus display is used to provide the essential information for glider pilots without unneccesary overhead.
- The documentation starting point is here: https://github.com/larus-breeze/doc_larus
- 57mm display unit. With transflective 2" display or a round 2.1" Display, STM32H7 and Rust firmware.
Sensor hardware containing an IMU, pressure sensors and a (D-)GNSS The sensor firmware is providing essential information for glider navigation like
- Position (Precision GNSS),
- AHRS = Attitude including true heading, optionally with D-GNSS satellite-based heading
- GNSS/INS-based ultra-fast variometer
- Real-time wind measurement
- Air-density measurement
- Automatic 3D high precision compass calibration
- Worldwide automatic adaption to the local magnetic induction parameters using NOAA data
- Connectivity via CAN, Bluetooth or WLAN, RS232 and USB
The Larus project maintains a Software-In-The-Loop SIL-Simulator to test and qualify algorithms.
Some more details about the features can be found under algorithms.
The sensor unit can also be used as a universal data logger for manned or UAV test flights with a sampling-rate of 100 Hz. The logger can write it's data to a micro-sd with a virtually unlimited capacity.
Fully assembled unit with single GNSS
