Radiolink SE100 GPS module for Pixhawk


Anybody know anything about this one? It's $35 from Roboshop:

  • 2.5dbI high gain and selectivity ceramic antenna
  • MMIC BGA715L7 from Infineon power amplify IC
  • SAWF (Surface acoustic wave filter) form Murata
  • HMC5983 from Honeywell geomagnetic

The Radiolink SE100 GPS Module for PixHawk exceed the limitation of IC sensitivity index from circuit schematic design to PCB placement.1 meters positional accuracy, positioning in 23 seconds and valley station keeping ability.


  • Positional Accuracy: 1m precision when working with concurrent GNSS, 2.5m precision when working with single GNSS
  • Velocity precision: 0.1m/s
  • Max height: 50000m
  • Max speed: 515m/s
  • Max acceleration: 4G
  • Max update rate: up to 18Hz
  • Sensitivity Tracking & Nav.: -167dBm; Reacquisition:-163dBm; Cold start:-151dBm; Hot start:-159dBm
  • Time to first fix: Cold start: 26s, Hot start: 1s
  • Connect ports
  • Power supply: voltage 3.3VDC+-5%, current 50~55mA


  • A.GPS UART interface, baud rate: 1.2K/4.8K/9.6K/19.2K/38.4K/57.6K/112.5K
  • B.Geomagnetic I2C interface

  • Hey Markus.

    Could you please tell me which droteck GPS exactly you mean?


  • I have this gps is not good the droteck is 2x better , droteck 15sat hdop 0,78 radiolink 7sat hdop 2,05

  • This would seem to emphasize the importance of good GPS antennas.

  • see RC Tech.se description....

  • Ceramic? Weight/dimensions? Those specs are not even on the radiolink website.

  • Distributor

    Is that pure Kryptonite in the center of it?

  • I wonder what the actual performance is like?  As we know, the specific implementation actually does matter.  Just because the same chips are employed, does not mean the performance will be the same as properly engineered alternatives.
