Heavy Vehicle Guidance
The mining and constructions industries today rely very heavily on GPS monitoring, tracking and navigational data and this is primarily because highway constructions, surveyors and marker pegs have been replaced with in-cabin vehicle guidance and control systems for excavators, graders, bulldozers and road paving machines.
These modern and advanced specialty vehicles enable their highly trained drivers to program their vehicles to respond to pre-programmed site plans, thereby enabling the vehicles to achieve close tolerance parameters for position, level and gradient. GPS technology is specifically integrated for high-precision applications in open-cut mines such as vehicle and equipment tracking and mine asset management. In such hi-technology integrational applications, GPS critical data is acquisitioned and decoded by sophisticated IT systems and meshed with other engineering applications to provide multifunction guidance and control. Companies that have integrated their vehicles and mine management systems include Leica Geo-systems, Topcon Positioning Systems and Trimble / Caterpillar.
Surveying, Mapping and Geophysics
Advanced GPS survey-grade technology utilize L1 and L2 signal frequencies to position survey markers, buildings, bridges, airports, harbors, railway stations and various other large infrastructures. This technology is also used to determine aerial mapping, terrain data, through the Geographical Information System (GIS) applications.
GPS is widely used in the acquisition of terrain and aerial mapping data, sensitive physical formations such as volcanoes and earthquake fault lines and the tracking / monitoring of seismic and incipient activities. This important seismic data is transmitted to TV and other news channels for early warnings to the public so that adequate precautionary measures are taken well in time.
One of the major highlights in the characteristics of GPS satellite technology is the accuracy, reliability and stability in the synchronicity of its technology and this has proven to be very compatible for telecommunications applications. It has been observed that GPS synchronized technology enables adequate synchronization of Coordinated Universal Time (UTC) time through the resolution of signals from discrete atomic clocks at specified locations. Although ground-based Chip Scale Atomic Clocks (CSAC) are quite accurate for this purpose, the synchronization of the CSACs is rather problematic without the GPS satellite technology.
As the local and international markets are fast globalizing, the global finance system that enables, governs, schedules and prioritizes digitalized monetary transactions, funds transfers and audit trails is becoming more and more contingent upon high precision time systems. Today, 80% of the millions of daily global retail transactions are done through credit and debit cards. GPS satellite technology integrates perfectly with on-board atomic clocks in order to allow high-speed and high precision local and global transactions.
