Pulsar navigation using time of arrival (TOA) and time differential TOA (TDTOA)

Acta Astronautica, 2018
Abstract Pulsar navigation is a novel autonomous navigation method for deep-space missions. The pulsar navigation method using the time of arrival (TOA) determines the absolute position of the spacecraft. However, its accuracy is greatly affected by system errors, including the ephemeris error of the pulsar and the satellite-borne clock error.

Time of arrival (TOA)-based direct location method

2015 16th International Radar Symposium (IRS), 2015
The presented direct location method computes the 3D position of an object using exactly four time-of-arrival (TOA) measurements, i.e. range measurements, to four reference points or stations. This operation is also commonly known as multilateration. Traditionally, this problem can also be solved using three TOA measurements to three reference stations,
