Satellite Navigation
A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows satellite navigation devices to determine their location ( longitude, latitude, and altitude/ elevation) to high precision (within a few centimetres to metres) using time signals transmitted along a line of sight by radio from satellites. The system can be used for providing position, navigation or for tracking the position of something fitted with a receiver (satellite tracking). The signals also allow the electronic receiver to calculate the current local time to a high precision, which allows time synchronisation. These uses are collectively known as Positioning, Navigation and Timing (PNT). One set of critical vulnerabilities in satellite communications are the signals that govern positioning, navigation and timing (PNT). Failure to properly secure these transmissions could not only disrupt satellite networks but wreak havoc on a host of dep ...

IRNSS-1B satellite has two payloads: a navigation payload and CDMA ranging payload in addition with a laser retro-reflector. The payload generates navigation signals at L5 and S-band. The design of the payload makes the IRNSS system interoperable and compatible with Global Positioning System (GPS) and Galileo. The satellite is powered by two solar arrays, which generate power up to 1,660 watts, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft Launched In 2015
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to supp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Communication-Centric Intelligence Satellite (CCI-Sat)
Communication-Centric Intelligence Satellite is an Indian advanced reconnaissance satellite, being developed by the Defence Research and Development Organisation (DRDO). It will be India's first officially declared dedicated spy satellite and is expected to be in orbit, tentatively, by 2014. This satellite will help Indian intelligence agencies to significantly boost surveillance of terror camps in neighbouring countries. Utilisation The CCI-Sat will be able to capture images, eaves drop on communication (for example, a conversation between two satellite phones) and perform surveillance. It will be equipped with a synthetic aperture radar to take high-resolution images of target regions. The cost of the satellite is expected to be around ₹ 100 crore (around US$25 million). ISRO will contribute towards the satellite's design and development and the Defence Electronics Research Laboratory (DLRL) will be responsible for manufacturing the payload.Bhargavi, Kerur"India's Spy ...

Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satish Dhawan Space Center
Satish Dhawan Space Centre - SDSC (formerly Sriharikota Range - SHAR) is a rocket launch centre ( spaceport) operated by Indian Space Research Organisation (ISRO). It is located in Sriharikota, Tirupati district of Andhra Pradesh. Sriharikota Range was renamed in 2002 after ISRO's former chairman Satish Dhawan. History Sriharikota island was chosen in 1969 for a satellite launching station. The centre became operational in 1971 when an RH-125 sounding rocket was launched. The first attempted launch of an orbital satellite, Rohini 1A aboard a Satellite Launch Vehicle, took place on 10 August 1979, but due to a failure in thrust vectoring of the rocket's second stage, the satellite's orbit decayed on 19 August 1979. SHAR was named as 'Satish Dhawan Space Centre SHAR' (SDSC), on 5 September 2002, in memory of Satish Dhawan, former chairman of the ISRO. The SHAR facility now consists of two launch pads, with the second built in 2005. The second launch pad was used for lau ...
