Abstract
A system rapidly orients a phased array antenna with respect to a transmitter by performing carrier phase tracking, resolving integer cycle ambiguities for multiple baselines in the array antenna, and solving parameters describing the platform orientation. The phased array antenna may be placed on a stationary platform, such as a base station, or on a mobile platform, such as a drone or a car.
Claims15
A method, comprising:
- receiving, by a phased array antenna for a platform, one or more carrier signals;
- tracking carrier phase of the received one or more carrier signals;
- resolving, by one or more processing elements for the platform, one or more integer cycle ambiguities for one or more baselines associated with the phased array antenna;
- and
- solving, by the one or more processing elements, one or more orientation parameters based on the one or more integer cycle ambiguities, wherein the one or more orientation parameters describe orientation of the phased array antenna.
2 more elements
An apparatus, comprising:
- a phased array antenna receiving one or more carrier signals;
- a receiver performing carrier phase tracking of the one or more carrier signals received by the phased array antenna;
- and
- one or more processing elements programmed to:
- resolve one or more integer cycle ambiguities for one or more baselines associated with the phased array antenna;
- and
- solve one or more orientation parameters based on the one or more integer cycle ambiguities, wherein the one or more orientation parameters describe orientation of the phased array antenna.
4 more elements
A system, comprising:
- a set of satellites configured to transmit one or more carrier signals;
- and
- a mobile platform comprising:
- a phased array antenna attached to the mobile platform and configured to receive one or more of the one or more carrier signals from the set of transmitters;
- a computing entity programmed to:
- perform carrier phase tracking of the one or more carrier signals received by the phased array antenna;
- resolve one or more integer cycle ambiguities for one or more baselines associated with the phased array antenna;
- solve one or more orientation parameters based on the one or more integer cycle ambiguities, wherein the one or more orientation parameters describe orientation of the phased array antenna;
- and
- cause a change in the orientation of the phased array antenna based on the solved one or more orientation parameters to direct transmission of data from the mobile platform to the set of satellites.
