Scope

Scope: This standard specifies the overall technical requirements for the construction of low-orbit Internet of Things satellite communication systems in forest fire prevention communication systems. This standard applies to the design, equipment selection, and technical indicator selection during the construction of low-orbit satellite IoT communication systems in forest fire prevention communication systems. Main technical content: 5.1. Space Segment Resources The satellite network utilizes geostationary satellite transponders. In the UHF frequency band, it should support working either separately or simultaneously on multiple satellite transponders. The satellite selected for forest fire emergency communication should cover all forest areas in China, and the satellite signal in the northeast and southwest regions of China should be locally strengthened. The specific technical indicators are as follows: a) The minimum equivalent isotropic radiation power (EIRP) of the satellite UHF band in the forest area should be no less than 47dBW; b) The quality factor (G/T) of the satellite UHF band should be no less than 0Dbw/k; c) The satellite transponder should have a linearizer; d) The traveling wave tube amplifier power should be no less than 140W. 5.2. Operating Frequency Band There are two operating frequency bands: — Uplink frequency band: 240MHz-243MHz; — Downlink frequency band: 318MHz-320MHz; 400.2-401MHz; 5.3. Network Service Platform The satellite network uses IP as the carrier platform for all network services, supporting the transmission of IP data, IP voice, and IP video. Each terminal of the satellite network equipment should support IPv4, IPv6, TCP, UDP, IGMPv1, IGMPv2, RIP1, RIP2, ICMP, ARP, FTP, SMTP, SNMP, H.323, and SIP protocols. 5.4. Transmission Service Types The network provides comprehensive services such as voice, video, and data. 5.5. Link Transmission Quality Requirements The availability of the one-way satell
