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. 

   
DP-filter
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.
