Understanding Age of Corrections in PointPerfect L-band Delivery

For customers accustomed to IP-based correction services, where correction ages are typically around 1-5 seconds, the 30-second correction age seen with L-band delivery may raise concerns. However, this is a normal characteristic of L-band transmission, which involves more transmission paths and higher latency compared to the faster IP method. In open-sky environments, an average correction age of 30 seconds is expected and does not affect performance. PointPerfect's hybrid PPP-RTK service is designed to operate reliably with these higher correction ages, maintaining precision and accuracy. As long as corrections remain under 60 seconds, the service functions as intended; beyond this threshold, the F9 module will revert to 3D/DGNSS to ensure reliable positioning data.
