Product overview

The ComNav SinoGNSS K700 GNSS OEM board provides an entry-level positioning engine for precision agriculture, GIS, mobile and handheld applications. It tracks GPS L1, BeiDou B1 and GLONASS L1, with support for WAAS, EGNOS, MSAS and GAGAN SBAS services. Positioning options include standalone, SBAS, DGPS and single-baseline RTK, alongside post-processing. Its SinoGNSS DP-filter delivers 20cm pass-to-pass accuracy without correction input for precision agriculture. Single-baseline RTK accuracy is 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically.

The board measures 71mm × 41mm × 11mm and weighs 18g. Its hardware includes a 2 × 12 pin male I/O connector, one 50 Ω MCX female antenna connector and three LED status indicators. It accepts +3.3 V~ +5.5 VDC input and consumes 0.6 W. Operating temperature spans -40 °C to + 85 °C, with humidity tolerance of 95% without condensation. PPS output and Event Marker input support timing functions, while position data output options include ASCII, ComNav Binary and BINEX, with selectable rates of 1 Hz, 2 Hz, 5 Hz, 10 Hz and 20Hz.
