METHOD AND SYSTEM FOR IMPLEMENTING A DUAL-MODE DUAL-BAND GNSS/M-LMS PSEUDOLITES RECEIVER
First Claim
1. A method of determining a position of a mobile cellular communication device, the method comprising:
- receiving a pseudolites signal in a first frequency band at an antenna of the mobile cellular communication device;
converting the pseudolites signal from the first frequency band to a corresponding positioning signal in a Global Navigation Satellite System (GNSS) frequency band; and
determining the position of the mobile cellular communication device at the GNSS chipset of the mobile cellular communication device using the converted positioning signal.

Abstract
A method, device and circuit for determining a position of a mobile cellular communication device is disclosed. A pseudolites positioning signal is received in a first frequency band at an antenna of the mobile cellular communication device. The pseudolites signal is converted from the first frequency band to a Global Navigation Satellite System (GNSS) frequency band to obtain a corresponding positioning signal in the GNSS frequency band. The converted positioning signal is delivered to a GNSS chipset of the mobile cellular communication device. The GNSS chipset determines the position of the mobile cellular communication device using the converted positioning signal.
