r1288 r1289 220 220 <p><a name="co"><h4>4.6. Clocks & Orbits</h4></p> 221 221 <p> 222 BNS requires GNSS clocks and orbits in the IGS Earth-Centered-Earth-Fixed (ECEF) reference system in SP3 format. They can be provided by a real-time GNSS engine such as RTNet. In contrast to SP3, the incoming clocks must have been corrected for the 2nd-order relativistic effect. This 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. 223 </p> 224 225 <p> 226 The sampling rate should not be much greater than 10 sec. Note that otherwise in IP streaming involved tools on the NTRIP Broadcaster or client side may respond with a timeout. 222 BNS requires GNSS clocks and orbits in the IGS Earth-Centered-Earth-Fixed (ECEF) reference system in SP3 format.
