  Paksat-MM1

The Paksat-MM1 is Pakistan's second communication satellite, which was launched on 30 May 2024. [1] [2] This mission was a joint effort of the Space and Upper Atmosphere Research Commission (Suparco) and the China Aerospace Science and Technology Corporation. [3] The satellite was launched from China's Xichang Satellite Launch Centre. [4]

Naming

Before launch, the satellite was designated PakSAT-MM 1R, but at launch it was referred to as PakSAT-MM 1.

The satellite was launched on LM-3B launch vehicle, which was the 96th launch of the LM-3B launch vehicle and the 524th launch of the Long March family. [5]

Details

The satellite was developed by China Academy of Space Technology (CAST), a subsidiary of CASC. It is based on the DFH-4E satellite platform with a liftoff mass of 5,400 kg, and equipped with 9 antennas and 48 transponders in C, Ku, Ka, and L bands. It can provide various services such as broadcasting, regional enhanced communications, high-throughput broadband and the Satellite-Based Augmentation System (SBAS) services etc. The satellite will be positioned at 38.2° E orbit slot, covering the mainland and surrounding areas of Pakistan, parts of the Indian Ocean, the Middle East, East Africa, and parts of Europe, with a service life of 15 years. [6]

Total deliverable capacity of Ka-Band is 10 Gbps covering whole Pakistan, there is no steerable beam in Ka-HTS payload. Maximum throughput achievable on a single beam is approx. 1 Gbps. User beams are fixed and cannot be steered over any particular area. For PakSat-MM1 HTS, three Gateway beams have been designed over Lahore, Karachi and Islamabad with gateway beam of 0.08°. It is recommended to install two gateways (one primary and other as back up). However, PakSat-MM1 HTS has been designed in such a way that one GW can handle all the traffic of 11 user beams. [7]

Satellite Internet access is Internet access provided through communication satellites; if it can sustain high speeds, it is termed satellite broadband. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using the Ku band to achieve downstream data speeds up to 506 Mbit/s. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space.

NigComSat-1 was a Nigerian communication satellite. The initial contract to build the satellite was signed in 2004. It was launched in China by Nasrda and became the third African geosynchronous communication satellite, when it was launched at 16:01 UTC on 13 May 2007, aboard a Chinese Long March 3B carrier rocket, from the Xichang Satellite Launch Centre in China. The spacecraft was operated by Nigerian Communications Satellite Ltd (NIGCOMSAT). On November 11, 2008, NigComSat-1 failed in orbit after running out of power due to an anomaly in its solar array.

Paksat-1,, was a geosynchronous and communications satellite built and owned by the Boeing Company, leased to the Space & Upper Atmosphere Research Commission (SUPARCO) and renamed Paksat-1. It was successfully put on orbit on 1 February 1996 as Palapa-C1 for Indonesia as its original customer. But, after the technical problems, the satellite was leased to SUPARCO at an orbital location of 38° East longitude in December 2002. Paksat-1 offers the C-band and Ku-band coverage in over 75 countries across Europe, Africa, Middle East, South and Central Asia. Its customers included government organizations, television broadcasters, telecommunications companies, data and broadband internet service providers.
