BNS allows to configure two Ephemeris Corrections streams refering do different reference systems for upload to different NTRIP broadcasters. You may use this functionality for parallel support of a backup NTRIP broadcaster or for simultaneous support of two reference systems. +
+ ++When using clocks from Broadcast Ephemeris (with or without corrections) and clocks from SP3 files in the same application, it is important to understand that Broadcast Ephemeris clocks - according to the Interface Control Documents (ICD) - are corrected for the 2nd-order relativistic effect whereas clocks from SP3 files are not. The 2nd-order relativistic effect is a priodic time correction defined as -2 (R * V) / c^2 and includes the scalar product of satallite position and velocity divided by the speed of light raised to the second power.
