Introduction

The K801T module is a high-performance, low-cost GNSS module launched by ComNav Technology latest. It can meet the demand of nanosecond level timing accuracyand ideal for timing applicationsand solutions such as Internet of Things, 5G mobile networks and robotics.

Support BDS-3, BDS-2, GPS, GLONASS, Galileo, NavIC
Support L1/L5 bands
5ns timing accuracy
Surface-mounted design to integrate
Internal adaptive anti-interference algorithm
0.15W low power consumption

Multi-constellation dual-frequency

K801T adopts high-precision Soc chip and supports BDS-2, BDS-3, GPS, GLONASS, Galileo, QZSS and NavIC, receives L1/L5 dual-frequency signals,which can significantly reduce signal acquisition time under interrupted situations and improve timing accuracy

Adaptive Anti-interference Technology

The power consumption is lower to 0.15W. Built-in anti-multipath and anti-interference technologies can improve anti-interference capbility so that effectively mitigates the multipath effect in urban canyons, and improve timing reliability and stability in complex environments

High Precision Timing Technology

The K801T GNSS module delivers timing accuracy at the nanosecond level for critical infrastructure applications. Its multi-band functionality minimizes timing discrepancies to under 5ns in clear sky conditions, eliminating the dependency on external GNSS correction services

Easy to Integrate

Featuring surface mounted design, smaller size of 12mm × 16mm and low power consumption, K801T is compatible with mainstream GNSS modules, allowing users to integrate more easily
