Systems Engineering Software
Telesat has developed a suite of systems engineering software tools designed specifically for satellite operators. These software programs were developed and tested by Telesat to perform very specific satellite system design work in the manner required by design engineers. Telesat owns the intellectual property rights for the programs and can make them available to customers by means of a licensing arrangement. The available software programs are described below.
IMSHI
Program IMSHI computes the carrier-to-third-order intermodulation noise ratio for carriers that share the same non-linear amplifier which exhibits AM/AM and AM/PM characteristics such as a TWTA. The program can handle more than 100 carriers of user defined frequencies and power levels. The TWTA characteristics are specified by a data file containing the AM versus AM and AM versus phase shift transfer curves. The program runs on Windows 9x or NT 4.0 or Windows 2000.
ASIAP
The main function of this versatile and very comprehensive software package is to provide the user with analysis tools required in the evaluation of intersystem interference between geostationary satellites. It can also display orbital characteristics of low-earth-orbit or inclined-orbit satellite systems. With its graphic user interface, the software also allows the user to visually inspect and analyze the coverage areas of any user-specified satellite constellation arrangement. The site license is restricted to a maximum of five (5) copies because this program utilizes a third party software. The program runs on DOS or Windows 9x.
CKLINK
This is an easy-to-use but versatile program to perform satellite link budget calculations for FDMA channels. The program computes link budgets for both in-bound and out-bound links between a home station and a remote station. The program assumes that the satellite transponder is operated in the linear region as most FDMA channels do. The program runs on Windows 9x or NT 4.0 or Windows 2000.
SUNTR
The purpose of this program is to calculate the date, time, duration and C/N degradation of outages due to sun transit for one or more receiving earth stations for a given year specified by the user. The program runs on Windows 9x or NT 4.0 or Windows 2002.
FLUXD
The purpose of this program is to predict the microwave flux density level in the vicinity of one or more transmitting earth stations for the purposes of microwave radiation hazard evaluation and the determination of safety antenna fencing dimensions. The program runs on DOS or Windows 9x.
PSKNL
This program allows the user to simulate a digital link and compute the link's bit error rate in the presence of Gaussian thermal noise and signal distortion due to band-limiting filtering and non-linearity. BPSK, QPSK, Offset QPSK and MSK modulation can be simulated by the program. The program runs on Windows 9x or NT 4.0 or Windows 2000.
