IRNSS-1I
IRNSS-1I is an Indian navigational satellite that forms part of the Indian Regional Navigational Satellite System. IRNSS-1I is the ninth satellite launched for the IRNSS constellation and one of five IRNSS satellites currently operational. The satellite is intended to replace the failed IRNSS-1A, and complete the constellation of geosynchronous navigation satellites after IRNSS-1H failed to do so. The satellite's assembly, integration and testing is partly done by a consortium of six small firms led by Alpha Design Technologies, a Bengaluru-based aerospace firm under URSC's supervision. Payload Like its predecessor, IRNSS-1I has two types of payloads, navigation payload and the ranging payload. The navigation payload transmits navigation service signals to the users. This payload is operating in L5 band and S band. A highly accurate rubidium atomic clock is part of the navigation payload of the satellite; failure of these rubidium atomic clocks was the reason IRNSS-1A was dee ...

Indian Regional Navigational Satellite System
Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC (acronym for Navigation with Indian Constellation; also, 'sailor' or 'navigator' in Indian languages), is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending around it, with plans for further extension up to . An extended service area lies between the primary service area and a rectangle area enclosed by the 30th parallel south to the 50th parallel north and the 30th meridian east to the 130th meridian east, beyond borders where some of the NavIC satellites are visible but the position is not always computable with assured accuracy. The system currently consists of a constellation of eight satellites, with two additional satellites on ground as stand-by. The constellation is in orbit as of 2018. NavIC will provide two levels of service, the "standard positioning service", which will be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NVS-01
NVS-01 is the first in the series of second generation navigation satellite and the ninth satellite in the Indian Regional Navigation Satellite System (NVS), with an alternate name of, IRNSS-1J. It will augment the existing satellite and bolster the capability of the NavIC constellation by adding more robustness and new features. ISRO already launched IRNSS 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H and 1I. The satellite is intended to replace IRNSS-1G and augment the constellation of geosynchronous navigation satellites after IRNSS-1I. Payload NVS-01 has two types of payloads, navigation payload and the ranging payload. The navigation payload transmits navigation service signals to the users. This payload is operating in L1 band, L5 band and S band. A highly stable Rubidium atomic clock is part of the navigation payload of the satellite. Failure of the imported Rubidium atomic clocks across the fleet of previous generation of satellite led to the creation of an indigenous optio ...

PSLV-C41
PSLV-C41 was the 43rd mission of the Indian Polar Satellite Launch Vehicle (PSLV) rocket. It was launched on Thursday, April 12, 2018, at 04:04 Hrs (IST) by the Indian Space Research Organisation (ISRO) from the first launch pad of the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh. This was the 12th mission to use the PSLV XL configuration. This mission launched IRNSS-1I navigation satellite into orbit. The satellite is intended to replace the failed IRNSS-1A, and complete the constellation of geosynchronous navigation satellites after IRNSS-1H failed to do so. The satellite was successfully infected into orbit 19 minutes after lift-off. ISRO Chairman K. Sivan described the mission as a success and congratulated the scientists behind it. Payload Like its predecessor, IRNSS-1I has two types of payloads, navigation payload and the ranging payload. The navigation payload transmits navigation service signals to the users.

IRNSS-1A
IRNSS-1A is the first navigational satellite in the Indian Regional Navigation Satellite System (IRNSS) series of satellites been placed in geosynchronous orbit. Satellite The satellite has been developed at a cost of , and was launched on 1 July 2013. It will provide IRNSS services to the Indian public, which would be a system similar to Global Positioning System (GPS) but only for India and the region around it. Each IRNSS 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 inter-operable and compatible with GPS and Galileo. The satellite is powered by two solar arrays, which generate power up to 1,660 watts, and has a lifetime of ten years. Launch The satellite was launched from the Satish Dhawan Space Centre (SDSC) on 1 July 2013 at 11:41 PM ( IST). The launch was postponed from its initial launch date ...

ECEF
The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as ''X'', ''Y'', and ''Z'' measurements from its center of mass. Its most common use is in tracking the orbits of satellites and in satellite navigation systems for measuring locations on the surface of the Earth, but it is also used in applications such as tracking crustal motion. The distance from a given point of interest to the center of Earth is called the geocentric distance, , which is a generalization of the ''geocentric radius'', , not restricted to points on the reference ellipsoid surface. The geocentric altitude is a type of altitude defined as the difference between the two aforementioned quantities: ; it is not to be confused for the '' geodetic altitude''.
