GUIDE-K35E Three-Sample Vehicle Route Performance

Following a factory supply-chain adjustment for GUIDE-K35E, we re-evaluated positioning performance and sample-to-sample consistency. Three units running the same algorithm on the same hardware platform were tested concurrently on one vehicle route, against a 10 Hz reference trajectory.

Test Notes

Reading this test

Stable RTK accuracy in favourable conditions.

The residential segment shows closely matched results across all three samples.

Shared conditions do not produce identical solution histories.

Nominally identical units can reach or recover Fixed at different times and behave differently in Float.

Fixed status is not an accuracy guarantee.

Read the solution state together with measured positioning error.

Degraded-state behaviour drives the larger full-route differences.

Float and DR periods contribute most to the separation. Repeated campaigns are needed to establish persistent unit differences.
