Specifications

NOTE: Control points uploaded to ProMark3 RTK have

always their coordinates converted to WGS84. When

you select a control point for use as the base position,

these coordinates are again converted, this time to the

coordinate system (see

page 237) and map datum

(see page 238) used in the ProMark3. The converted

coordinates are displayed in the Location and Elevation

fields.

• Manual entry: Tap successively inside the Location and

Elevation fields and enter the known coordinates. Make

sure your entries are compatible with the coordinate

system (see page 237) and map datum (see

page 238) used in the ProMark3.

4. Tap Start. The ProMark3 RTK starts operating as a base.

RTCM 3.1 corrections are now broadcast via the radio

modem. The screen shows

the following parameters:

• Site ID: As a reminder

• Elapsed: Time elapsed since you started the base sta-

tion

• # Sats: Current number of satellites received

• PDOP: Current PDOP value

• Base Station Position: 3D coordinates of the point above

which the base is installed.

• Power indicator (all green: fully charged)

• Free memory indicator (all green: maximum)

Later, after you have finished your survey and you come back

to the base to switch it off, first tap Stop. The ProMark3 RTK

will instantly stop transmitting RTCM corrections.
