Matek Systems SAM-M8Q GPS Module Support GLONASS Galileo QZSS SBAS for RC Drone FPV Racing
Specification: Brand name: matek Item name: SAM-M8Q GPS module Dimensions: L26 x W16 x H7.5 mm Weight: 7 gram Input voltage range: 4~6V Uart (Tx,Rx) interface Battery for HOT module start Power LED(Red) & Time pulse LED(Blue) Baudrate 9600 default Can be easy mounted in your case by double sided tape Supported by INAV/Betaflight/Ardupilot, ect.
-On-board Ultra low noise 3.3V voltage regulator and RF filter for noise blocking
-Features an additional front-end LNA for optimized performance and a front-end SAW filter for increased jamming immunity
-Build-in embedded GNSS patch antenna, low power consumption
-The 15 x 15 mm patch antenna provides the best compromise between the performance of a Right Hand Circular Polarized (RHCP) antenna and a small size to be integrated in any design.
-Max navigation update rate
Single GNSS up to 18 Hz
2 Concurrent GNSS(GPS & GLONASS) up to 10 Hz
-Horizontal position accuracy(GPS & GLONASS) 2.5 m CEP
-Velocity accuracy 0.05m/s
-Cold start 26 s
Aided cold starts: 2 s
Hot start 1 s
-Sensitivity
Tracking & Navigation: –165 dBm
Reacquisition: –158 dBm
Cold start: –146 dBm
Hot start: –155 dBm
Tips:
-GPS, GLONASS, SBAS, QZSS are enabled by default
-Blue PPS LED blinking(1Hz) means 3D fixed
-update rate 1Hz & baudrate 9600 default
-Baud 9600~115200 supported by INAV
-BF doesn’t support GPS position hold and RTH, GPS Rescue mode is supported by BF3.5 or last.
-The scratches on ceramic antenna are the result of tuning the antenna by ublox. Placing small nicks in the centre of the long edges, or corners, brings them into spec.
