GPSL20/25M SA/HA 25Hz Plug & Play GPS receiver for MoTeC systems and BMW Motorrad
Introducing our latest product, GPSL20M/25M for all NMEA RS-232 MoTeC systems.
GPSL20M/25M MK3
Smaller GPSL20M/25 is now available. Main differences are:
- Antenna connector and wiring comes now straight from the unit, not in an angle as before.
- Casing is now smaller and lighter
Electronics are the same as before.

Now also compatible with BMW Motorrad motorcycles.
Lightweight but still strong, made to anodized aluminum casing. Weatherproof since potted.
Accuracy
Our devices are accurate since all modern GNSS systems are supported. Device will work in all continents with high accuracy.
Other advantage is that the cheap antenna is separate and the receiver itself can be installed into a safe location.
Device can be connected to any voltage between 5 to 32V. This is important so that the GPS can be moved from the sensor voltage line and will not affect other sensors.
Device is available in two versions:
- SA: Standard Accuracy, 2m
- HA: High Accuracy, <0.5m
Difference to old GPSL20M/25M is that HA device supports multiple bands, SA device supports only L1 band.
Devices use the same construction and devices can be distinguished from the color of the LED.
Below is the result from one of our tests. Test is made on purpose in a very challenging location with high hills around the road.
