3 AIMMS-20 SETUP AND CALIBRATION
3.1 Preparation of Laptop / Computer
The first step in setting up your AIMMS-20 system is to install the aimcfg software
utility provided with the system onto a laptop computer which will be used to interact
with the system. The laptop will require an RS232 serial communications port, either
built into the computer or as a PCMCIA or USB peripheral adapter. Instructions on
installing the software are provided in Section 4.1.
Before proceeding further, you should first familiarize yourself with the aimcfg PC-
based software utility. The aimcfg User’s Manual is provided as Section 4 of this
document.
3.2 Measurements
Two pieces of information will be required concerning the physical installation on
your aircraft. First, the straight-line distance between the two GPS antennas,
referred to as the antenna baseline, must be measured (see Fig. 6). This can be
determined from known station information utilized for the unstallation, or measured
directly using a plumb-bob first to mark the position on the ground directly below the
each antenna, then measuring the distance between these two marks on the
ground using a long tape measure. Similarly, the location of the ADP relative to the
aircraft centreline needs to be determined, referred to as the ADP Offset. This is the
straight-line distance from the centre of the probe to the centreline of the aircraft.
The ADP Offset is positive if the ADP is located on the starboard wing and negative
if located on the port wing. Retain these measurements for later input as part of
AIMMS-20 configuration setup using the aimcfg software utility.
