SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
Note: When the aircraft is stationary the field may appear as ¾’s.
2. Report Items: 5 & 17, 8 & 20, and 21
Some other commonly used report items, used in the testing or
troubleshooting of the system, are shown in
Figure 4–29. These report items
shown are only available to Level 2, maint access users.
Note: Depending on the version of software installed, and the user’s
selection of reports, the maintenance utility program report items
displayed may differ from those shown in the example
illustrated Figure 4–29.
Note: Signal strength values (C/no=) in early versions of software do not
show the decimal point. If operating HSD transceivers with earlier
software, divide the C/no value by ten.

Report 23
Item Number
Description
1 IRS lat/long as interpreted by the HSD
2 Aircraft pitch angle, where “UP” is +ve
3 Aircraft roll angle, where clockwise (cw) is +ve
4 Aircraft heading; where the nose of the aircraft is pointing, based on yaw
offset
5 Aircraft true track; direction the aircraft is flying—not necessarily the
direction it is pointing (See NOTE)
6 Aircraft velocity
7 Time, based on the system real time clock
8 Doppler frequency offset; increases with velocity (See NOTE)
9 Antenna azimuth pointing to the satellite, with respect to the nose of the
aircraft
10 Antenna elevation angle to the satellite, with respect to the horizontal
position of the aircraft
11 Ocean Region the system is logged-on to
12 Reported antenna gain and the selected antenna, port or starboard
13 Indicates the channel card for which results 14) to 17) relate to
14 RF input Carrier-to-Noise (C/No) level; typically 50.0 to 55.0
15 RF input signal level; typically –12.0 to –18.0 when not ”in call”: *not to
exceed 0 when “in-call”
16 HSD internal LRU temperature
17 System call status
18 Satellite beam the card is registered on
