1. 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.

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

16. 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. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. 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. - View Dependent Claims (27, 28)
zeroing a plurality of terms in said first set of terms.

28. The method of claim 27 wherein said adjusting step further comprises:
adjusting a plurality of non-zero terms in the second set of terms in response to the effects of zeroing terms in the first set of terms.

29. 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. - View Dependent Claims (30, 31, 32, 33)
