TRUE VIEW 410 FIELD OPERATIONS

1. BASE STATION

The True View 410 records GNSS signals during flight which will be corrected later in EVO. This type of
system is known as a PPK system. Base station processing methods should be considered during the
planning process because the user will need to determine how they plan to correct their flight data
before collecting. True View GNSS signals can be corrected by one of three methods:
1. Single base – Single base, as the name implies, is a static recording from one single base
station which is close in proximity to the flight area. Corrections are computed at the base
station, then applied to the data collected by True View. CORS stations can also be used for
single base processing if they are within 12 miles of the flight area and record static data at 1Hz.
The base station must also record both L1 and L2 signals and must be during the same time as
the flight. Single base is the only processing method if you plan to process with the
selected.
2. SmartBase – SmartBase is a cloud processing option that uses multiple CORS stations to
compute base corrections for your flight. Smart base processing allows for longer baselines
from the flight area and the user does not have to setup a base station or download CORS data
from a nearby station. This option still requires an existing CORS network in the area of flight.
Users can go online to the
covered by the SmartBase network and estimate the quality of the results.
3. PP-RTX – PP-RTX is a cloud processing option that does not require a base station or CORS
network. PP-RTX corrections can be computed anywhere. Accuracy is reduced using this
method, but can be used as a last resort option in the event of base station failure or lack of
CORS network.
