• The number of satellites in view
• 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 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, Pinnacle).
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 HiPer+ and a Computer” on page 2-5 for this
procedure.
2. Open PC-CDU, click Configuration->Receiver
->MINTER and specify the following parameters, then
click Apply (Figure 3-2 on page 3-7):
• Recording Interval – 15 seconds
