Abstract |
: |
In order to ensure successful operation, to avoid harmful interference, and to observe the procedures of the ITU Radio Regulations, a RF System, prior to its operation, has to carry out interference and compatibility analysis to seek a co-ordination agreement with a number of administrations, which have filing priority in respect of their Radio-communication Networks. In cases where the geocentric angle separation of the nominal orbital positions between the subject satellite network pairs is less than 8°, then the network would be subject to coordination in accordance with the provisions of the Radio Regulations. The satellite networks having orbital separation less than 8° that require detailed interference and compatibility analysis and frequency coordination with the affected radio-communication systems.
The paper will demonstrate a case study of detailed Interference and Compatibility Analysis of MEASAT networks vis-à-vis affected satellite networks having the orbital separation less than 8°.
In this paper, we will also review advanced methodologies and techniques used for interference and compatibility analysis of radio communications systems.
MEASAT-1 was launched in January 1996 to the orbital location of 91.5ºE utilizing the C and Ku-band frequencies. MEASAT-1 provides C-band coverage over the East Asia Region in the frequency range 5925-6425 MHz and 3700-4200 MHz, while Ku-band covers Malaysia, Indonesia, Philippines and India in the range 13.75-14.5 GHz and 10.95-11.2 GHz, 11.45-11.7 GHz & 12.2-12.75 GHz.
MEASAT-2 was launched in November 1996 to the orbital location of 148ºE also utilizing the C and Ku-band frequencies. MEASAT-2 provides C-band coverage over East Asia, Australia and Hawaii in the frequencies range 5925-6425 MHz and 3700-4200 MHz, while Ku-band covers Malaysia, Indonesia, Vietnam, Taiwan, Philippines and Eastern Australia in the range 13.75-14.5 GHz and 10.95-11.2 GHz, 11.45-11.7 GHz & 12.2-12.75 GHz.
In addition to MEASAT-3, there are also plans by BSS to launch two other satellites, MEASAT-1R and MEASAT-5 (or A-M SAT). MEASAT-5 will be launched to the orbital location of 5.7°E carrying 24 C-band and 12 Ku-band transponders. In the C-band, MEASAT-5 will carry a wide beam covering the African continent, while Ku-band will comprise of two beams, one fixed over Southern Africa and another with steerable capability.
