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.

  • 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

Ports

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

I am finding this Radiolink module to be much better than my previous Chinese clone ublox M8N GPS module. Positional drift on the ground is within a metre with around 15 satellites. I hope this means I wont have to climb over fences and wade through fields of stinging nettles to retrieve my drone ever again.
