Abstract
GenetScope
The GenetScope propagation model is
based on work of Dr.
Under direction of the HFGCS System
Program Office, the Defense Information Systems Command (DISA), Joint
Interoperability Test Command (JITC) tasked Northrop Grumman Information
Technology to develop an updated version of the NETSIM-SC model. Subsequently
working with the
The GenetScope/NETSIM2 HFGCS model
provides Air to Ground, Ground to Air, and Ground to Ground traffic and High
Frequency (2-30 Megahertz) propagation simulations on a worldwide model. The Propagation model is based on the
National Telecommunications and Information Administration (NTIA), Institute
for Telecommunication Sciences (ITS) VOACAP and ICEPAC propagation models.
The NETSIM2 model is based on
Military Standard specifications for HF Radio (MIL-STD 188-141B), HF Data
Modems (MIL-STD 188-110B), and NATO Standardization Agreement (STANAG) 5066
protocols. The model can also
provide basic HF radio point to point voice and data simulations using
worldwide predictions of HF propagation conditions.
Additional information on the
GenetScope/NETSIM2 model may be obtained from the JITC.
ICEPAC
The Ionospheric Communications
Enhanced Profile Analysis and Circuit Prediction Program (ICEPAC) predicts the
expected performance of high frequency (HF) Broadcast systems, and in doing so
is useful in the planning and operation of HF transmissions for the four
seasons, different sunspot activities, hours of the day, and geographic
location.
This High Frequency (HF) planning
software was developed by:

BACKGROUND on ICEPAC
For many years, numerous
organizations have been employing the HF spectrum to communicate over long
distances. It was recognized in the
late 1930's that these communication systems were subject to marked variations
in performance. The effective operation of long-distance HF systems increased in
proportion to the ability to predict variations in the ionosphere, since such an ability permitted the selection of optimum frequencies,
antennas, and other circuit parameters.
Research demonstrated that most variations in HF system performance were
directly related to changes in the ionosphere, which in turn are affected
in a complex manner by solar activity,
seasonal and diurnal variations, as well as latitude and longitude. Various organizations developed computer
models to analyze HF circuit performance.
The Ionospheric Communications Analysis and Prediction Program (IONCAP)
developed by ITS and its predecessor organizations became one of the more
accepted and widely used models for HF propagation predictions. However, IONCAP demonstrated poor performance
in the polar region and used some of the older electron density profile
structures. To correct these
problems, IONCAP was transformed into ICEPAC by adding the Ionospheric
Conductivity and Electron Density
(ICED) profile model described in Tascione
(1987). The ICED profile model is a
statistical model of the large-scale features of the northern hemisphere. The model recognizes the different
physical processes that exist in the different regions of the ionosphere. It
contains distinct algorithms for the sub-auroral
trough, auroral zone, and polar cap.
