Nowadays, a growing number of GNSS users demand highly-accurate positioning with minimal latency. PPP is a new positioning technique providing centimeter-level error. Precise Point Positioning (PPP) processes measurements from a single user receiver, using detailed physical models and corrections, and precise GNSS orbit and clock products computed beforehand.

In the so called Tri-Valley Universityí in California, USA.
Students were allegedly duped and framed.
Now, tagged with GPS ankle-bracelets.
By the officials of Immigration and Customs Enforcement.
Why so?

In a modern mobile mapping system, the navigation component usually consists of a GPS receiver and an inertial navigation system (INS), which can provide accurate geo-referencing to the imaging sensors [1][2]. To achieve centimetre-level positioning accuracy, RTK-GPS is a natural choice. However, RTK-GPS in urban areas suffers from frequent outages due to blockages of either the GPS signals or the reference station radio links. In addition, multipath from buildings, trees and heavy vehicles could degrade the accuracy of the GPS when the vehicle is near them.

NRSC inducts state of the art Airborne Large Format Digital Camera into service
National Remote Sensing Centre, Hyderabad, India has inducted state of the art Airborne Large Format Digital Camera (LFDC) into the country and successfully carried out the first operational task during December, 2010 over 10 towns in Chhattisgarh state for the Department of Land Records, Government of Chhattisgarh. NRSC utilized it Super King Air B -200 aircraft fitted with Computer Controlled Navigation System (CCNS), Gyro stabilized mount and Kinematic GPS system (KGPS) for the survey.

Consumers share uneasy relationship with LBS
Location-based advertisements prompt nearly half of customers to take action, says a new study from Microsoft. The Microsoft-commissioned research in the UK, Germany, Japan, the U.S. and Canada, and found that 18% of consumers (22% in the U.S.) have seen an advertisement based on their location. Of those, 46% have taken action, including redeeming the coupon offered or visiting the store. Nine in 10 users think location-based ads are useful.

JAXA selects Spirent for Multi-GNSS Testing
To further the development of the Quazi-Zenith Satellite System (QZSS) program, the Japanese Aerospace Exploration Agency (JAXA) has selected Spirent Communications’ testing solutions to verify performance of its satellite receivers. JAXA is using Spirent’s GSS8000 Multi-GNSS Constellation Simulator.

Japan keen to own navigation satellite system
Japan is considering launching new satellites to establish its own global navigation satellite system (GNSS) in a bid to reduce its reliance on GPS network. The country aims to make it 10 times more accurate than GPS. The satellites would be of the same type as the so-called quasi-zenith satellite, Michibiki, or of a geostationary type. The project is being drafted by the Strategic Headquarters for Space Development headed by Naoto Kan, Prime Minister, Japan.

Law to ensure optimum use of geospatial tech in Delhi
A year after the Delhi government, India, launched its much-publicised INR 120-crore geo-spatial project to map the land and utility service records of the city, it has been observed that its officials prefer sticking to the old ways. Hence the Delhi State Government is now planning to enact a law to ensure that its officials use the technology in everyday applications.

Wikileaks syndrome affects Galileo project
Berry Smutny, CEO of OHB-System, has lost his job because of Wikileaks. He was reported in a Wikileaks’ cable to have told US diplomats that Europe’s Galileo satellite-navigation project was a “stupid idea”. Although Smutny has denied the cable’s contents, OHB’s board has decided to remove him from his post.
