REAL Positioning Engine

REAL Positioning Engine

The RANSAC (Random Sample Consensus) based autonomous integrity monitoring algorithm is integrated for the observation anomalies caused by multipath and interference in urban environments. It can monitor pseudo-range, carrier phase, and Doppler observations in real-time and accurately eliminated the faulty satellites, thus achieving more stable positioning results.

Epoch Differential Smoothing Technology

Epoch Differential Smoothing Technology

The movement of the user is calculated by using the carrier phase difference between the adjacent epochs, performs fusion filtering with the RTK positioning result to have a smoother solution. all the tracked satellites of the rover are fully used in the solution when the base station satellite is blocked, and the smooth positioning result can still be maintained when the RTCM correction data is interrupted for a long time.

Carrier Half-Cycle Ambiguity Repair Technology

Carrier Half-Cycle Ambiguity Repair Technology

In the urban dynamic environment, the loss of lock and re-tracking of the carrier phase are frequent. After re-tracking, the frame synchronization (Frame Sync) is needed to eliminate the half-cycle ambiguity and then used for the RTK integer ambiguity solution. Bynav receiver integrates carrier half-cycle ambiguity repair technology based on navigation message prediction and matching (patent authorized), which quickly eliminates half-cycle ambiguity, thus improving satellite availability, and effectively shorten the recovery time.
