• If the receiver should function as a Base, ensure it has the
proper configuration. See “Configuring the Receiver” on
page 3-2 for details.
• If the receiver should function as a Rover, ensure it has the
proper configuration. See “Configuring the Receiver” on
page 3-2 for details.
D The corresponding receiver options may be disabled or expired.
• See “Managing Receiver Options” on page 4-14 for details
on how to check current options.
• Order a new OAF with the desired options activated to
enable or extend validity of the corresponding receiver
options. Contact your dealer or visit the Topcon website at
www.topconpositioning.com for details.
• Refer to the PC-CDU Reference Manual for a detailed
description of options.
D There are not enough common satellites. In order to obtain a
fixed solution, the Base and Rover should track at least five
common satellites.
• Ensure that both the Base and Rover receivers use the same
updated almanac. See “Collecting Almanacs and
Ephemerides” on page 2-14.
• Check the elevation masks of the Rover and Base receivers;
they should be the same. See page 3-5 for information
about setting the elevation mask.
D A discrepancy exists between the differential standards used at
the Base and Rover receivers.
Ensure the Base and Rover receivers use the same corrections
input/output format:
1. Connect your receiver and a computer, and start PC-
CDU. See “Connecting the Receiver and a Computer” on
page 2-15.
2. Click ConfigurationReceiver and the Ports tab. Use
the same input/output format for both receivers.
