Abstract
According to some embodiments, a method performed by a wireless device comprises: receiving a broadcast of full ephemeris data for a serving cell satellite, the broadcast of full ephemeris data occurring at a first periodicity; determining a position of the serving cell satellite based on the full ephemeris data; receiving a broadcast of delta ephemeris data for the serving cell satellite, the broadcast of delta ephemeris data occurring at a second periodicity more frequent than the first periodicity; and determining a position of the serving cell satellite based on the full ephemeris data and the delta ephemeris data.

A method performed by a wireless device, the method comprising:
- receiving a broadcast of full ephemeris data for a serving cell satellite, the broadcast of full ephemeris data occurring at a first periodicity;
- determining a position of the serving cell satellite based on the full ephemeris data;
- receiving a broadcast of delta ephemeris data for the serving cell satellite, the broadcast of delta ephemeris data occurring at a second periodicity more frequent than the first periodicity;
- and
- determining a position of the serving cell satellite based on the full ephemeris data and the delta ephemeris data.
A wireless device comprising processing circuitry operable to:
- receive a broadcast of full ephemeris data for a serving cell satellite, the broadcast of full ephemeris data occurring at a first periodicity;
- determine a position of the serving cell satellite based on the full ephemeris data;
- receive a broadcast of delta ephemeris data for the serving cell satellite, the broadcast of delta ephemeris data occurring at a second periodicity more frequent than the first periodicity;
- and
- determine a position of the serving cell satellite based on the full ephemeris data and the delta ephemeris data.
A method performed by a network node, the method comprising:
- transmitting a broadcast of full ephemeris data for a serving cell satellite, the broadcast of full ephemeris data occurring at a first periodicity;
- and
- transmitting a broadcast of delta ephemeris data for the serving cell satellite, the broadcast of delta ephemeris data occurring at a second periodicity more frequent than the first periodicity.
