Abstract
Generating signals from non-GNSS transmitters, and processing the signals using a GNSS positioning module. Systems and methods identify a chipping rate, identify a PN code length, generate a PN code that has a length equal to the identified PN code length, generate a positioning signal using the identified chipping rate and the generated PN code, and transmit the positioning signal from the transmitter. The PN code length may produce, at the identified chipping rate, a PN code duration that is equal to or is a multiple of a PN code duration used in a GNSS system, the identified chipping rate may be equal to or a multiple of a chipping rate used in a GNSS system, and the identified PN code length may be equal to or a multiple of a PN code length used in a GNSS system.
