SCOPE OF FIRST PHASE
Deployment of an integrated instrumental
system to continuously measure, monitor,
process, store, assimilate and distribute high
precision and low latency data of horizontal and
vertical geodesic positioning from permanent
and temporary GNSS stations in continental and
oceanic islands of Brazil.

EQUIPMENT & SITE REQUIRENMENTS
Equipments and mechanical support:
the art sensors and
components that were designed and built for the intended climate and
areas subjected to a high rate of deterioration, such as high
humidity in the Amazon region and salinity of the air at sites located
near the ocean.
site locations to have an
geographic and tectonic distribution; ideally with equidistant spatial
site separation, in order to monitor translation and rotation of the
Local Geology and Monuments:
ideally construction should be in
bedrock; away from known faults; Reinforced concrete pillars for
survey monuments, at least 2m into subsurface are required in
Weather and Sky Conditions:
The ideal meteorological parameter is a
clear and dry sky with no air pollution;
Radio Frequency, Acoustic and Electromagnetic Interference:
should not be located in the path of, or near the emitters of radio,
television, or microwave signals in the sensitive frequency regions in
the band of 1.1
1.6 GHz range; Also, explosions and the 60Hz
electrical energy noise should be avoided.
the viewing horizon should have a 5
elevation and obstruction free view over 95% of the horizon.
Reflective surfaces, bodies of water, cliffs, walls and metal walls
should be avoided because of GNSS multipath interference from
structures (particularly metal), including wires separated by 15 to
25 cm and metallic fences, within 100m of the GNSS antenna.
adequate to transmit a stream of data
electronically for rapid processing, ideally broad
communications for near real
time data transfer, instrument
control and monitoring. Must have data safeguard against
communication and power failures.
Power system & lightening protection:
robust, reliable solar
power generation with sufficient backup to maintain continuous
operation; underground cable guides to avoid impacts or damage
Site Security and Safety:
to protect the equipments and
monuments that might be destroyed, vandalized, or stolen.
