Calculating Time Offsets

Q: How do you deal with timing differences between GNSSs? 

A: All GNSSs inherently depend on precise timekeeping to measure the satellite/receiver time of flight of signal propagation with sufficient accuracy to compute ranges/distances for multilateration calculations. Each GNSS ground segment therefore dedicates considerable effort to maintaining a highly stable atomic time scale as well as the corresponding offset to global standards such as UTC (Coordinated Universal Time).

MUSTER

Existing methods for improving the GNSS performance commonly attempt to enhance the signal processing and navigation estimation parts of a single receiver. Such approaches, however, leave unexplored the potential benefits inherent to the integration of data from multiple receivers.

North Korea’s GPS Jamming Prompts South Korea to Endorse Nationwide eLoran System

North Korea’s GPS Jamming Prompts South Korea to Endorse Nationwide eLoran System

Projected accuracy and coverage of Korea’s eLoran network. Ministry of Oceans and Fisheries of Korea

GPS jamming attacks from North Korea that have increased in frequency and duration since they began August 2010 have prompted the South Korean government to implement an enhanced Loran (eLoran) systems that will cover the entire country by 2016.

The South Korean government completed design, development, and construction documents for the eLoran system in February and will procure the system infrastructure through international competitive bidding.
