Embedded with QUANTUM III SoC chip, the K803 Lite is capable of tracking all running and planned constellations, improving the availability and reliability of GNSS positioning. |
The K803 Lite module largely reduces the sudden position jumps via DP-filter algorithm, providing a smooth positioning trajectory in single-point positioning mode. |

Pass-to-pass |
Based on the GNSS signal carrier phase and Doppler observations, the K803 Litecan provide a smooth and accurate trajectory without GNSS correction data input. Theoretically, the velocity accuracy of the moving carriers calculated via Doppler frequency shift can reach 1cm/s, which is ideal for some dynamic applications. |
Pass-to-pass error is based on the position offset between the desired track spacing and the actual track spacing calculated by GNSS receivers. Over a 15-minute time window, 95% of the pass-to-pass error of K803 Lite is within 12cm, and the overall error value is within 15cm. |
PASS-TO-PASS ACCURACY
Taking full advantage of single-frequency GNSS carrier phase and Doppler
observation,K803 Lite provides a smooth and accurate pass-to-pass solution for relevant applications. With the help of the DP-filter algorithm, the relative accuracy of K803 Lite between 2 consecutive epochs is within 1cm in single point positioning mode. For longer periods like 15-30 min, the pass-to-pass accuracy can 15cm in 95% of the cases. |
