K803 Lite Smooth Positioning Solution for Precision Agriculture
SOLUTION
With full-constellation tracking, low power design, DP-filter smooth positioning capabilities, the K803 Lite GNSS board is an ideal solution for precision agriculture, machine guidance and other system integrations.
CORE TECHNOLOGY
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. |
SUPPORT PRODUCT
Featuring with high gain, low noise amplifier, high sensitivity and full-con-stellation tracking capability, AT360 is a good choice for users to develop systems or solutions for land survey, agriculture, machine control and deformation monitoring.
