ABSTRACT

Since 2000 in Bulgaria have been installed and put into operation two DGPS
beacons. Preliminary site selection and equipment delivery procedures for
a new station of the same type have been started recently. Each of the two
existing and one planned stations serve specific activities: marine and inland
water way navigation and exploration, land navigation, positioning, targeting,
etc. Though built with different purposes and missing a common network
concept, these stations provide differential correction coverage over a part of
the national territory good enough to allow for submeter real-time positioning
accuracy for mapping and GIS data collection.
The existing signal reception conditions are explored and analyzed using radio
planning and field surveying methods. Some conclusions are drawn with
regard to further development and achievement of nation-wide DGNSS signal
coverage.
