Low Cost GPS/Glonass Receiver for Automobile, Marine
and Portable Applications
Introduction
Korean company is offering technology of low cost GPS/Glonass
receiver for automobile, marine and portable applications.
With its advanced design channel architecture, 16 universal
channels "Agro-16" receiver can receive and
process either GPS or Glonass satellite signals thus
giving high performance with flexibility and versatility.
16 is the sufficient number for channels to provide
highest performance with low cost and low power consumption.
With the addition of GLONASS, the increased number of
available satellites allows wider satellite coverage
for position computation. It provides better position
information in the areas where the satellites are liable
to be blocked. The adaptive AGC (automatic Gain Control)
scheme used in the receiver further enhances the reception
of satellite signals resulting in better signal tracking
as well as wider satellite coverage. The position accuracy
with GPS alone can be severely degraded to the error
of 100 m due to the influence of SA (Selective Availability).
Stand-alone GPS/GLONASS position accuracy is typically
within 10m. The addition of GLONASS not only improves
the position accuracy but greatly enhances the velocity
accuracy as well. The enhancement of position and velocity
accuracy provides greater potential for integrated or
hybrid navigation systems, which are gaining more popularity
among many commercial applications. In addition to the
standard features for differential corrections (RTCM),
"ARGO-16" receiver is designed to fully support
and process upcoming WAAS (Wide Area Augmentation System)/EGNOS
(European Geostationary Navigation Overlay Sytem), which
will provide comparable position accuracy without the
corrections from remote reference stations.
