Introducing our latest product, GPSL25B for all NMEA RS-232 Bosch systems, ECU's and displays.

Lightweight but still strong, made to anodized aluminum casing. Weatherproof since potted.

Cheap antenna is separate and the receiver itself can be installed into a safe location.

 

GPSL25B MK3

Smaller GPSL25B 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.

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.

Accuracy

Device is available in two versions:

• SA: Standard Accuracy, 2m
• HA: High Accuracy, <0.5m 

Difference to old GPSL25B 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.

For comparison, here is the result against competitor GPS against 2 laps with GPSL25B HA
