Record and Replay Signals for the Sporting …

It has been a journey

From apprehensions to aspirations,

Enthusiasm to endurance,

Potential to performance.

It is not about desires

But more of deliverables.

Classification deals with creation of class, which corresponds to a meaningful grouping of locations. Grouping performs combination of two or more area features into a single area feature. Symbolization is polygon to point symbolization process. Simplification removes unwanted detail from a linear geometry by

Theoretically in the simultaneous observation of the high-precision GPS network solution mode, the selection of the independent baseline vector can be arbitrary with the same adjustment. But in the real situation, the results varies in different selections for the model of baseline solution is imperfect[1].

Galileo is Europe’s contribution to the multi-GNSS to provide a highly accurate, guaranteed global positioning service under civilian control. Offering dual frequencies as standard, Galileo is expected to deliver extremely good realtime positioning accuracy. From users’ point of view, availability of Galileo’s signal would help in achieving a multi- GNSS environment for redundancy and system independence.

The International Maritime Organisation (IMO) is developing e-Navigation as the future approach to marine navigation in order to enhance maritime safety. As such, the IMO state that positioning systems for e-Navigation “should be resilient …. robust, reliable and dependable. Requirements for redundancy, particularly in relation to position fixing systems should be considered”

In recent years there has been an explosion in the sporting world in the use of GPS. You will scarcely see a runner or cyclist on the road without either a smartphone strapped to their arm, or a dedicated GPS device clamped to their handlebars, tracking their every move. The amount of information that the modern sportsperson – from casual amateurs to full time professionals – is logging, analysing, and sharing is phenomenal. There are now dozens of ways of uploading data for the whole world to share and study.

Coordinates 100th Issue is indeed a milestone. Just like in cricket or baseball scoring a century or a home run does not come in every innings except for the very gifted and talented. However, in the case of Coordinates it is very welcome and heartening to note that the journal is endurable, enduring and is producing a kind of a continuing dialogue that many subscribe to.

CHC has announced the availability of the LT400HS a rugged 120-channel GPS+GLONASS Handheld Receiver designed to achieve sub-meter SBAS positioning to centimeter accuracy in RTK networks. It is the most cost-effective and powerful GNSS Solution for Survey, Construction and GIS Professionals. It is the perfect choice for companies which have not yet invested in GNSS technology due to cost or/and occasional equipment use. www.chcnav.com
