How is Trimble getting ready with the multi-GNSS systems scenario?: Trimble understands that our customers want to purchase receivers today that will benefit from the GNSS signals planned for the future. To keep up with these ongoing changes Trimble’s integrated circuit design team is constantly developing custom chips to be used in our receivers. With many divisions of Trimble utilizing this same core technology the economics of creating a new chip at frequent intervals makes more sense. The latest generation of receiver technology tracks the current Compass navigation demonstration system open service signals and Galileo open service under a license of the European Union and the European Space Agency.

What is the mandate of National Coordination Office for Space-Based PNT?: The mandate for the National Coordination Office (NCO) is detailed in United States (U.S.) National Policy. Our primary role is to support the National Space-Based PNT Executive Committee which convenes at the Deputy Secretary level to advise and coordinate on Space-Based PNT issues affecting multiple departments and agencies. The NCO does not make decisions or create policy. Rather, we serve as the Executive Committee’s Secretariat and execute tasks as directed by them. Specific responsibilities include interagency coordination, consensus development and issue resolution for all matters presented to the Executive Committee. As Director, I represent the Executive Committee on space-based PNT matters within the Government, the public sector, and with representatives of foreign governments and international organizations.

While surveying and surveyors flourishes, In Far East and South East Asia, Countries like India are an enigmatic and intriguing case. Despite a great history and legacy, The challenge to prepare and groom surveyors,
To meet the present day needs and demands,Apparently, looks huge.

As traffic jam is getting a bad reality in our times, realistic information on the traffic situation together with optimized routing to reduce overall waiting time on the trip become more and more valuable all over the world. But how to vlaidate, if the information provided is reliable and trutsworthy? On the first look, this sounds easy, but as truth is in the details, a lot of hurdles have to be passed for a successful finish.

It is a battle about resources, which is scarce and precious
It is about spectrum.
Stakes are high and consequences are serious.
When in January this year, the Federal Communications Commission
(FCC) gave conditional approval to LightSquared,
To roll out its ground based wireless network (4G).
GPS community got nervous.
As testing indicates that LightSquared’s ground-based transmissions
overpower the relatively weak GPS signal …

What has triggered the idea of National GIS?

The idea of National GIS (NGIS) has been driven by the needs of the Planning Commission, Government of India. The Planning Commission looks for lot of information which helps them in the process of planning. The need has been felt to integrate many of these information so that they can utilized effectively for various planning processes and applications.

Guidance and steering control systems that are now in widespread use by farmers for ploughing and cultivating the land with unprecedented accuracy, require centimetre-level position as well as attitude information accurate to a few degrees. Additionally, position and attitude update rate of no less than 10Hz is required for successful guidance in agricultural environments. Guidance and steering control systems rely particularly on heading and roll measurements to steer the tractor on parallel straight lines or curves known as plough lines.

A S (quasi-zenith satellite), which was anticipated to be the original Japanese positioning satellite, was launched in September, 2010. As an augmentation system of GNSS, two MTSATs had already been put into orbit and their main purpose is to broadcast the correction data for wide-area DGPS. This has actually improved the accuracy of wide area DGPS as a result of reception of the correction data from MSAS (MTSAT Satellite-based Augmentation System). The QZS also enhances the ranging function and it already has signal characteristics for the GNSS that are expected in the near future.
