• The satellite geometry (DOP)
• The antenna’s location
• The ionospheric activity level
• The types of receivers used
• The accuracy requirements
• The necessity of resolving carrier phase ambiguities
Generally, single-frequency receivers are used for baselines
whose lengths do not exceed 15 kilometers (9.32 miles). For
baselines of 15 kilometers or greater, use dual-frequency
receivers.
Dual-frequency receivers have two major benefits. First, dual-
frequency receivers can estimate and remove almost all
ionospheric effect from the code and carrier phase
measurements, providing much greater accuracy than single-
frequency receivers over long baselines or during ionospheric
storms. Secondly, dual-frequency receivers need far less
observation time to reach the desired accuracy requirement.
After the survey completes, data the receivers collect can be
downloaded onto a computer and processed using post-
processing software (for example, Topcon Tools).
The procedure that follows describes the steps the operator
should take to perform a Static Survey using MINTER.
1. Connect your receiver and computer. See “Connecting the
Receiver and a Computer” on page 2-11 for this procedure.
2. Open PC-CDU, click ConfigurationReceiver
MINTER and specify the following parameters, then
click Apply (Figure 3-2 on page 3-7):
• Recording interval – 15 seconds
• Elevation mask angle – 15 degrees
• File name prefix – last 3 digits of receiver serial number
