Abstract
A method and apparatus for creating and distributing satellite tracking data in a compact format to a remote receiver. At least a portion of the satellite tracking data is extracted from memory and is formatted into a compact format. The compact formatted data is transmitted to the remote receiver via a distribution network. Once this data is received at the remote receiver it is reformatted into a format prescribed by the remote receiver
Claims33
A method of creating and distributing compact satellite orbit models comprising:
- receiving satellite signals from at least one satellite and at least one receiving station;
- extracting at least a portion of the satellite tracking data from said satellite signal, representing said data in a first format;
- transmitting the formatted data to a remote receiver;
- and
- at the remote receiver, representing said formatted data in a second format supported by the remote receiver.
A method of creating and distributing a compact orbit model comprising:
- receiving satellite signals from at least one receiving station;
- extracting at least a portion of the satellite tracking data from the satellite signal, where said portion comprises a first number of orbit terms that define a first orbit model;
- formatting said portion to form formatted data having a second number of orbit terms that define a second orbit model, where said first number is greater than said second number;
- transmitting the formatted data to a remote receiver;
- and
- at the remote receiver, expanding the formatted data to have the first number of terms.
A method of creating a compact orbit model comprising:
- providing a satellite orbit model having a first set of terms;
- adjusting the first set of terms to produce a compact orbit model having a second set of terms, where a number of terms in the first set of terms is greater than a number of terms in said second set of terms.
Apparatus for creating and distributing compact satellite orbit models comprising:
- at least one satellite signal receiver for receiving satellite signals from at least one satellite;
- means for extracting at least a portion of the satellite tracking data from said satellite signal, representing said data in a first format;
- a transmitter for transmitting the formatted data to a remote receiver;
- and
- at the remote receiver, representing said formatted data in a second format supported by the remote receiver.
