GPS-Logger 3 – High-Performance 10 Hz Telemetry GPS
Precision flight data, perfected – at Aerobertics
The GPS-Logger 3 is a full-featured 10 Hz telemetry GPS system with micro-SD data logging, high-resolution TEK variometer, and an integrated 3-axis accelerometer.It replaces the GPS-Logger 2 and remains fully compatible, while introducing significant hardware and performance upgrades.
New Hardware – Version 3 Highlights
- New GPS module for superior reception, even in challenging conditions
- Further improved pressure sensors for finer variometer resolution with reduced noise
- Horizontally oriented TEK connector for easier installation, especially in narrow fuselages
Designed specifically for the demands of model aviation, the GPS-Logger 3 combines compact size and ultra-low weight with outstanding performance and flexibility.
Performance & Data Logging
With an adjustable recording rate of up to 10 Hz, the GPS-Logger 3 captures highly detailed flight data. Thanks to the micro-SD card, recording time is virtually unlimited and data access is quick and simple.
- Up to 10 measurements per second
- Data stored as plain text for easy processing
- Approx. 200 kB per minute at 10 Hz (up to 7 days on a 2 GB card)
Integrated Telemetry Support
Telemetry is a core feature of the GPS-Logger 3 and is fully integrated for 2.4 GHz systems with return channel, supporting:
- Jeti Duplex
- Multiplex M-Link
- Graupner HoTT
- Futaba
- JR DMSS
- FrSky
- Spektrum (via Spektrum adapter)
- PowerBox Core
The telemetry system only needs to be selected once via the GPS-Konverter PC software or UniDisplay.Factory default: Graupner HoTT.
High-Precision Variometer with TEK Compensation
An integrated high-resolution pressure sensor provides an extremely accurate variometer signal via telemetry.The built-in TEK port allows the use of compensation nozzles, ensuring true climb and sink indication, independent of control inputs (“stick thermals”).
For accurate altitude measurement even when using TEK compensation, a second independent pressure sensor is included, delivering speed-independent altitude data with automatic zeroing at power-up.
Advanced Sensors & Flight Analysis
- 3-axis accelerometer (±16 g) for load and maneuver analysis
- Acceleration values recorded at every waypoint and transmitted live via telemetry
- Integrated engine noise sensor (ENL) for automatic motor run detection
Competition-Ready
The GPS-Logger 3 fully supports competitive flight analysis:
Extended Data Integration
- Logs all Multiplex M-Link sensor bus data automatically (MSB data logger)
- Direct connection to UniLog 1 & 2 and UniSens-E for live data logging
- Receiver battery voltage recording included
Configuration & Data Evaluation
- Live data display and full configuration via UniDisplay
- Parameter setup via PC, UniDisplay, or telemetry
- 3D flight visualization using Google Earth™ with the free SM GPS-Konverter
- Supported by LogView and GNU DataExplorer (Windows, macOS, Linux)
Applications
Thanks to its compact size and low weight, the GPS-Logger 3 is ideal for:
- Gliders
- Aerobatic aircraft
- Helicopters
- HLG / DLG
- Slow flyers
- RC boats and cars
At Aerobertics, we value tools that deliver real data, real insight, and real performance—and the GPS-Logger 3 does exactly that.
