ISLAMABAD, Dec 27 (APP): Pakistan will launch its first indigenously developed communications satellite on August 14, 2011, from a facility in China and its life span will be 15 years.According to sources in Space and Upper Atmosphere Research Commission (Suparco), the satellite would be launched at a longitude of 38 degrees in geostationary orbit on the equatorial plane at an altitude of 36,000km above the earth’s surface.



Paksat-1R will carry a communications payload to facilitate the introduction of a range of new services, including broadband internet, digital TV distribution/broadcasting, remote/rural telephony, emergency communications, tele-education and tele-medicine.
The contract for Pakistan Communication Satellite (Paksat-1R) was signed between Suparco and China Great Wall Industry Corporation (CGWIC), a Chinese firm, on October 15, 2008, official sources maintained.

Work on the execution of the contract began soon after and is progressing as scheduled, the sources said, adding that the contract involved various other projects, including infrastructure and therefore it was difficult to invest an exact cost on the satellite itself.
Official sources further said that at least two new satellites Paksat-1R and Pakistan Remote Sensing Satellite (PRSS) – would be launched in the near future.

The satellites have been developed with technical and financial assistance of China.
At present, Pakistan has a communications satellite, Paksat-1, in orbit, providing coverage across Europe, Africa, the Middle East, Central Asia and the South Asian subcontinent.
It is being used by TV broadcasters, telecom companies, data and broadband internet service providers and government organizations.
Paksat-1R will replace Paksat-1, a leased satellite, to ensure continuity of service.

In 1990s, Pakistan also operated a small satellite, Badr-A, in low earth orbit. however, the country’s modest space programme has been oriented towards remote sensing applications.
Pakistan and China have agreed to enhance strategic coordination, advance pragmatic cooperation and work together to meet challenges in pursuit of common development.
In a joint statement issued after conclusion of Chinese Prime Minister Wen Jiabao’s visit to Pakistan, they declared 2011 as the “Year of China-Pakistan Friendship”, and decided to hold a series of activities in the political, economic, trade, military, cultural, sporting and education fields, to warmly celebrate the 60th anniversary of the establishment of Pak-China diplomatic relations.

They decided to further implement the Framework Agreement between SUPARCO and China National Space Administration (CNSA) on Deepening Cooperation in Space Science and Technology.
In this context, they expressed satisfaction on their joint collaboration in fabrication and launching of satellites.
When contacted, Paksat GM Col. Muhammad Latif confirmed that Pakistan’s new communication satellite would be launched in 2011.

maa shaaa ALLAH
 
well it was always 2 Satellites may be you didn't read properly

and yes its not 100% indigenous as various sources keep repeating. If that was 100% indiginous it would be built somewhere in Pakistan and hopefully launched in the same country. Chinese have played key role in these satellites but thats ok as llong as it is serving the purpose and hopefully we will be able to launch 100% indigenous satellites in future after these two
 
we should launch the remote sensing as soon as possible

we need tactical satellites in orbits

and after the first sensing satellite we should start manufacturing of another one with SAR capabiltty
 
It is great news in these difficult times we need much more good news like this
 
After successful launching and operation of BADR series of experimental satellites (BADR-1 and BADR-B) in the 1990s and early 2000s, SUPARCO now plans to launch high resolution remote sensing satellite system (RSSS) to meet the national and international user requirements in the field of satellite imagery.

A feasibility and system definition study was concluded in January 2007 which recommended the launch of a constellation of Optical and Synthetic Aperture Radar (SAR) Satellites to ensure that the domestic and international user requirements are competitively met. In this respect the RFP for RSSS consultancy services was launched in July 2007. Launch of RFP for the manufacturing of the satellite is planned in the third quarter of year 2008.

RSSS is planned to be a progressive and sustainable program. Initially, SUPARCO plans to launch an optical satellite with payload of 2.5 meter PAN in 700 km sun-synchronous orbit by the end of year 2011, which will be followed by a series of optical and SAR satellites in future. Necessary infrastructure for ground control and image reception and processing is also planned to be setup.
 
SUPARCO developed a Prototype Remote Sensing Satellite in 2007 as a part of skill development programme. It is an indigenous effort in the field of satellite engineering aimed at enhancing the know-how and capacity building of its scientists and engineers. Facilities developed/upgraded were utilized to test and evaluate the satellite responses in various environments such as HELMHOLTZ Coil, Clean Room, Anechoic Chamber and Light Controlled Environment, Satellite Platform Control Unit and Satellite Mission Control Room.

The Prototype satellite is the evaluation version of FM Satellite, in which Satellite Control, Navigation, Imaging, Communication and Power Management have been completely implemented.

The PRSS is able to acquire 2.5m GSD of satellite images. The PRSS Satellite is controlled through the OBC which can handle Telecommand and Telemetry through Ground Segment. All the subsystems of the Satellite are interconnected through CAN-2.0 Bus. The Power Capacity of PRSS is 600W with state of the art Power Management system which is used to perform Solar Power Distribution, Battery Power Distribution, Fast Take Over and Battery Charging Module and Subsystem Power Distribution through specific Power Control Unit which will manage the power according to specific requirements. In Satellite Navigation and Control system, PRSS is fully equipped with sophisticated Sensors and Actuators. The Satellite Navigation system comprises 3-Axis rate Gyros, Magnetometers, Accelerometers, Digital sun Sensor and Star tracking Sensors in order to provide accurate attitude and orbital determination. Magnetotorquer Rods, Thruster and Reaction wheels are used for controlling satellite attitude. The imaging Payload System is equipped with High resolution CCD sensor which is used in IKONOS, QUICKBIRD satellite for imaging with high speed Data Acquisition and Transmission to Ground Segment. The protocol implementation for communication of PRSS to Satellite Ground Segment is fully CCSDS complaint which can easily be interfaced with any standard Ground based equipments.

The prototype satellite has been integrated and tested under various conditions and through various testing tools in order to evaluate its performance and reliability.

RF Transmitter / Receiver

.

Along with digital expertise, PRSS team is also mature in RF areas. The PRSS Prototype is equipped with S-Band transmitter, supporting Data rate of 150 Mbps with direct carrier QPSK modulation scheme. Integration and testing of different transmitter modules was performed successfully. S-Band Telemetry Transmitter and Telecommand Receiver has been mounted on satellite.
 
Reaction Wheel and Propellant Tank

The reaction wheel mounted on the PRSS is used to perform actuation for compensation of orbital displacement in SPACE environment. The reaction wheel has been designed according to theoretical calculation of satellite environment. The pressure vessel design is essential because the propellant used for the thrusters needs to be stored in some storage device, the pressure vessel serves this purpose.

The storage tank was developed by using ASME Section VIII standards (the standards for pressure vessel). The pressure vessel is designed to store 30kg of propellant at high pressure without failure, with mass not more that of 10Kg.


Satellite Electrical Power System

PRSS Prototype Model is equipped with 600 watts Power System which has been developed and integrated with other subsystems. The power requirements of satellite Prototype comprises Solar panels of 32V and 11A, Battery Pack of 24V and 10A, fully regulated bus of 28V, Battery Discharge Regulators, Battery Charger (Fast and Trickle), Power Management and Control Unit. Separate Power distribution modules have been designed for individual subsystems with the provision of voltage and current monitoring.


Imaging Payload System

Functional testing of Imaging Payload of PRSS has been successfully completed. The Features of the Imaging Payload System are: KLI14403 Tri-linear CCD Sensors are used for imaging which have 3-Band sensor arrays with Resolution of 14400 pixels in line. High rate pixel output has been interfaced with 10MHz, 3-Parallel High Speed ADC with 12 Bit Resolution at 10MHz rate, Imaging Payload Controller on DM642 Media Processor Based Design for Managing System Tasks, Ethernet Based Image Data Transmission with CCSDS format at 100Mbps, UART Based IPC interface with CAN Controller, Telescope with 20m focusing for testing and evaluation of overall performance of sensor.
 
The Ground Segment Software has been developed for the acquisition of image data from satellite payload controller over Ethernet interface. It acquires and saves image data with time stamping and displays sub-sampled/low resolution image in the GUI. An Imaging Platform is designed to acquire the simulated earth images. Since the PRSS MSS sensor is push broom sensor therefore the moving platform is developed in order to test sensor and overall IPS electronics performance. This system is placed on PRSS Prototype Structure and its harnessing functional testing/debugging has been completed. Its software and hardware performance with power consumption log is measured and scrutinized with calculated system response which has successfully fulfilled all such requirement.
 
Engineering Qualified Model (EQM) of a Small Communication Satellite

As a first step towards the ultimate goal of achieving self-reliance in the field of design and development of communication satellites, SUPARCO has lately been involved in the design and development of prototype of a communication satellite named Prototype Paksat-1R. The project was completed in 2005. As a next step forward in achieving self reliance in development of a flight worthy satellite, SUPARCO now intends to develop the Engineering Qualification Model (EQM) of a small communication satellite. Engineering Qualified Models (EQMs) are more efficient and reliable / robust than prototypes but are not qualified to fly, for which Flight Models (FMs), that can withstand the rigours of launch and space environment, are required. To achieve this goal, EQM for 05 subsystems were designed and developed to be followed by the remaining ones to complete the satellite. The EQMs of the following subsystems were designed, developed and tested:

On-Board Computer (OBC)
Telemetry Subsystem
Telecommand Subsystem
C-band Transponder
S-band Communication subsystem
