Storage Auto Delete
Figure 40 - Configuration - Storage Auto Delete
This section is applicable for CCU firmware v2.0.x and later.
If “AutoDelete” is
true
(default)
, TrueView automatically deletes data from the UMS or camera SD
cards when the storage percentage reaches the “FreeSpaceHighThresholdPercent”. Folders will be
deleted until the "FreeSpaceLowThresholdPercent
”
is reached. Older files will be deleted first.
If "AutoDelete
”
is
false
, the user must manually delete data from the UMS or SD cards.
If storage space
is full, flight data will not be stored
.
TrueView 435 Field Operations
1.
Base Station
The TrueView 3DIS 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. TrueView 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 TrueView. 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
local
option
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.
