“Geography is our platform for understanding the world,” said Esri president Jack Dangermond in his opening remarks at the 2012 Esri International User Conference, held July 23–27 in San Diego, California, “and GIS makes geography come alive by condensing down data and knowledge into a kind of language that we can easily understand.”

Seven (7) of the nine (9) points which constitute the National GNSS Calibration Network were occupied using an active VRS receiver. This network of points will form the basis of legal traceability for Cadastral Surveys in Jamaica. The tables 4 and 5 below set out the results.

BeiDou is the Chinese pronunciation of the Big Dipper, which consists of seven stars located exactly at the north sky. Chinese people used BeiDou for identifying directions as long back as the ancient times. They also invented the world’s first navigation device based on terrestrial magnetism, the ancient compass, whose Chinese pronunciation is Sinan.

The project involves the establishments of a full complement of SBAS consisting of 15 Indian Reference Stations (INRES), 3 Indian Land Up-link Stations (INLUS), 2 Indian Master Control Centers (INMCC), 2 Geo-Stationary Navigation Payloads and with all the associated software and communication links.

High-performance autonomous pedestrian dead-reckoning (PDR) systems usually include 6 degrees-offreedom (DOF) inertial measurements unit (IMU) to calculate position of the user. These systems don’t rely on GPS signals and preinstalled infrastructure such as RF beacons, Wi-Fi routers, ultrasonic transmitters etc.

A casual Internet search can uncover much concern about the abruptness – and a potential for unnecessary “dodgesjust- in-case-the-azimuth direction…” – and the safety – of the climb / dive combination. Those and other capability restrictions are traceable to limited pre- GPS technology – highly dependent on transponders.
