This page
shows some componentry for the Omnistar DGPS system for
sub 1 metre accuracy.
To the left is the
backpack configuration for field use. This backpack can
be used with any Garmin GPS, or with any PDA or computer.
The DGPS can be set up more permanently
in a vehicle or boat. The backpack contains the power supply and
the DGPS box, and the antenna is mounted on the small
mast.
The Omnistar
receiver unit requires no attention from the operator.
It is completely automatic, tuning to the reference
station with the most integrity for the operating area.
Signal cost for one year is $2500 + GST = $2750. This
is separate to the hardware costs, shown below.
Info for under 5 metre accuracy. |
The Omnistar DGPS hardware is offered
in three variations for surveying and mapping work, as
well as for aircraft
and agriculture swathe guidance.
Modules can be supplied for any application, to work with any
type of "DGPS ready" GPS unit.

 OmniSTAR 7114LR12 (specs on PDF)
single, lightweight, and robust antenna housing, with batteries
in the backpack.

Both these systems use Everest Multi-Path
Rejection software, which improves accuracy by filtering
reflected GPS signals before they are processed by the DGPS receiver.
You can expect
improved accuracy under tree canopy, near buildings and other reflective
surfaces.
