| Abstract: |
| As an indispensable tool to develop and verify GNSS(Global Navigation Satellite
System) receivers, the nav
igation satellite signal simulator has been researched and developed extensively
for its academic significance and substantial commercial value. Development and
progress achieved in recent years on the theoretical research and products comm
ercialization of satellite signal simulators home and abroad are introd
uced and studied comparatively, including software simulator, hardware simulator
and hybrid structure simulator. New research progress achieved on main interrel
ated error models such as ionospheric error and multi-path effect is summarized
and analysed. Efforts that should be made in China on simulator products develop
ment, signal simulation theories study especially those related to error models
are pointed out. Finally future trends of the navigation satellite signal simula
tor are
discussed. |
