SE100 Introduction

RadioLink M8N GPS SE100, benefits from 22+ years of professional wireless experience of RadioLink engineers, exceed the limitation of IC sensitivity index from circuit schematic design to PCB placement.

50 centimeters position accuracy. Positioning 20 satellites in 6 seconds at open ground. Industry-leading valley station-keeping ability.

SE100 is suitable for all the open-source flight controller such as PIXHAWK, APM, NAZE32 and so on.

SE100 Configuration

GPS decoder chip: Radiolink SE100, with Ublox M10050, is much better than a single GNSS 7N.

Built-in high-precision electronic compass IST8310 (I2C port).

Antenna: 2.5dbI high gain and selectivity ceramic chip antennas

Power amplify IC: High-gain MMIC chip

Double Filter: two-stage SAWF (Surface acoustic wave filter) from Murata

Positioning Indicate

Humanized positioning green LED indicate. When SE100 is powered on, the indicators near the antenna are always on, when the satellite is found, the indicators near the antenna are always on, and the other indicators are blinking.

Definition of Connector

Connect to PIX: Red wire-VCC, White wire-TX, Orange wire-RX, Black wire-GND, Green wire-CLK, Yellow wire-SDA

GPS Mainboard: White wire-RX, Orange wire-TX, Red wire-VCC, Black wire-GND, Green wire-CLK, Yellow wire-SDA

Direction Indicate

Arrows shows the front, point to the same direction as the flight controller.

Keep the same direction with flight controller.

GPS connect to PIXHAWK 

6pin for GPS connect port: Pay attention to the installation direction,

the GPS direction is consistent with the flight control direction.

4pin for I2C connect port: Take off the internal compass of APM. Otherwise,

there is no data even if the GPS compass is plugged in.

Connect to APM

Compass Calibrate

Compass calibrate（Using version 1.3.39 of Mission planner）, please choose Pixhawk/PX4 if you use with PIXHWAK.

If you use with flight controller APM, please choose APM and External Compass and then click Live Calibration to calibrate the compass.

Calibrate like this picture shows, click Done to finished the calibrate. Click OK to save the settings.

If    , please try to cancel Compass #1 or Compass #2
