Abstract

With an increasing number of spacecraft targeting beyond the Earth's
orbit in recent years, autonomous navigation solutions have gained
importance. The availability of pulsar signals for simulations and HW testing is crucial to developing
pulsar-based navigation. While X-ray is preferred
for pulsar navigation sensors, the options for measuring pulsar signals
in X-ray is limited by existing space observatories. This work proposes
a method to build a surrogate pulsar signal model based on radio pulsar
observations. Pulsar selection usable for the actual radio telescope used is discussed, and a set of observations is realized. Measured data are processed
with PRESTO, and pulsar parameters for the model are derived. The proposed model expects all pulsar signal parameters to change in time. The resulting model can be the basis for all
known synthetic pulsar signal generators, allowing for a more realistic
resulting signal.
