SECORX is a subscription-based service providing over-the-air corrections for Precise Point Positioning (PPP). It uses TerraStar technology and brings sub-decimetre positioning to applications on land and up to 60 km offshore. SECORX-60 activation plans are available for a range of time durations to suit the needs of the user.
Dual-frequency code and Septentrio receivers combined with SECORX-C data with innovative error models and positioning algorithms to eliminate and decrease errors. Using GPS and GLONASS satellites enables the user of Septentrio receivers to maintain an accurate and reliable position in the most difficult of environments. Furthermore, it reduces the solution convergence time.
SECORX-D augmentation service delivers decimeter level position accuracy to land users globally. It provides more precision thanks to its resilience to satellite masking and ionospheric scintillation.
The service is based on Precise Point Positioning (PPP) techniques using both GPS and GLONASS where all GNSS system errors are removed or minimised by direct calculation, precise modelling or estimation.
The use of dual-frequency GNSS hardware in Septentrio’s receivers allows the calculation and removal of local ionospheric errors, while tropospheric delays are estimated within the calculation. Other sources of errors including ocean loading, earth tides and phase windup are also modelled.
SECORX-D provides better than 10cm horizontal and 20cm vertical accuracy (95%). These results make SECORX-D suitable for machine guidance and auto steer.
