Abstract
With the proliferation of global navigation satellite system (GNSS) enabled devices it has become more common for people to use it not only for car navigation but as well for personal navigation inside urban canyons. These environments are more difficult for GNSS devices due to stronger multipath and reduced sky visibility making it more prone for cycle slip appearance. This paper aims to provide a mechanism that relies on predicted Doppler measurements to perform data regeneration, when no signal is available or when a cycle slip is detected.
