eTesta GPSL50 MK3 50Hz Plug & Play GPS Receiver

New for 2025: 50Hz Serial GPS

Introducing our latest product, GPSL50 for all NMEA RS-232 MoTeC, Bosch and Solo (ECUMaster ADU) systems. Now also with 50Hz output rate including new VTG message.
 
The eTesta GPSL50 MK3 is a 50Hz plug & play GPS receiver designed for high-precision GNSS data acquisition, ideal for motorsport data logging and industrial monitoring and testing systems.

GPSL50M MK3

Several versions are available:

B Bosch (25Hz, 50Hz)
M MoTeC, BMW Motorrad (25Hz)
S Solo (20Hz)
G MoTeC 50Hz

Main differences to older MK2 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.

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.
