Product overview
The ComNav K801 GNSS Module is an embedded positioning component for applications that include UAVs, robotics, intelligent driving and Internet of Things systems. Its published architecture combines a high-precision SoC with an onboard IMU and an inertial navigation fusion algorithm. Surface mounting and dimensions of 12 mm × 16 mm × 2.4 mm define its board integration space; published weight is 1.6 g. The described product configuration is a GNSS module, rather than a flight platform or airframe-only kit.
Procurement should account for the module’s electrical, antenna and host-interface requirements. The manufacturer specifies +3.3 V ± 5% DC input and 0.15 W consumption with anti-interference enabled, alongside external LNA power requirements, suggested LNA gain and 50 Ω impedance matching. Interfaces include LVTTL, SPI, event marking, PPS and a status indicator. Accuracy figures depend on positioning mode: post-processing, single-baseline RTK, DGPS, SBAS and standalone operation have separate published values. Hot-start timing requires RTC, while CMR and CMR+ corrections are GPS-only. And host compatibility against these published qualifications.
