Abstract

A world map data base is processed by an APL program, called SATMAP, to represent the view of the earth seen from a satellite at any altitude, latitude, and longitude. The data base is processed by line segments characterized in terms of maximum and minimum latitudes and longitudes. This permits a more cost effective searching of the data base against a line-segment-visibility criterion than would be possible testing each point separately for visibility. The resultant view can then be presented on a suitable graphics and/or printer terminal such as a Tektronix 4015.

Analysis of satellite-induced factors affecting the accuracy of the BDS satellite differential code bias

Differential code bias (DCB) is one of the main error sources of the positioning, navigation and timing services and slant total electron content extraction. The DCB can usually be estimated together with ionospheric model coefficients from the data of ...
Precise orbit determination for BDS-3 satellites using satellite-ground and inter-satellite link observations

Since November 2017, eight BeiDou global navigation system (BDS-3) satellites equipped with Ka-band inter-satellite link (ISL) payloads have been launched into medium earth orbit. We present the precise orbit determination (POD) for BDS-3 satellites ...
NavIC Time Transfer With Satellite Common View

The present work analyses the use of common view time transfer in the Indian Regional Navigation Satellite System (IRNSS) with two different IRIMS (IRNSS Range and Integrity Monitoring Stations) as the reference station. IRNSS is an independent ...
