The Australian Communications and Media Authority (ACMA) has approved a number of trials of GPS repeating within road tunnels in Sydney and Melbourne.

ACMA said on Monday it was initially working with emergency services on the trials, which could result in a licensing arrangement for the devices.

Currently, the retransmission of a radionavigation-satellite service, which includes GPS, is currently forbidden by the Radiocommunications Act 1992 since it could interfere with signals. ACMA is in the midst of conducting a review of the ban.

“Should the trials be successful and the devices licenced for long-term use, the transport sector and general community would also benefit from enhanced in-tunnel navigation capability — including more accurate estimated times of arrival, and earlier warnings about in-tunnel congestion and lane changes,” ACMA said.

“The ACMA is also willing to consider applications from other transport authorities that are interested in trialling GPS repeaters in road tunnels.”

The Insatiable Need for the Latest Gadget

Many of you reading this are like me; you have to get your hands on the latest and greatest gadgets. Awed by the technology, features, and most current human achievements designed to dazzle your imagination. Many of these new devices are designed to either entertain, make our lives easier or both. People anxiously wait in lines outside stores, overnight sometimes, to get the latest gadgets spending hundreds or thousands of dollars on their shiny new device. An entire industry has subsequently been born for accessories to protect these devices. Cases, pouches, skins, screen protectors, guards, shields, and armors developed to keep your expensive new toys from baring scars from the abuses of daily life.

Scratches are one of my biggest fears when I get a new gadget. My latest toy, the HTC Google Nexus One, is my shiny new companion and daily I … Read More

Aviation

GPS technology is now very much prevalent in commercial aviation. Most commercial jetliners now increasingly employ GPS navigation for initial and non-precision approach to specified airfields. The Automatic Dependent Surveillance – Broadcast (ADB-B) is the futuristic primary guidance and navigational GPS technology for which a substantial amount of research, development and investments are being poured in. The ADB-B technology also involves direct inter-aircraft communication within a pre-defined radial proximity wherein it enables the aircraft to inter-communicate their relative speeds, distances, flight paths and locations. The development of this technology is not confined to any one country but is being developed globally through strategic technological multi-lateral alliances. Besides its use in commercial aviation, the GPS ADB-B technology is also being employed in the navigation Unmanned Aerial Vehicles (UAVs). The UAV’s are primarily used for resource mapping and air surveillance imaging – a task that was previously tasked to earth orbiting … Read More

Free GPS Software

May 1, 2020 | software | No Comments

I took a look at some of the online offers for free GPS software and found, like many “free” offers there were often limits and provisos involved. Often the freeware is a scaled–down version of purchasable products. Sometimes the free product has restricted functionality with features disabled, other products are trial–based and are disabled after a certain time (hours or days or use).

An example of limited free GPS software can be found at GPS Utility. The downloadable freeware is limited 100 waypoints and 500 track points. (There are 65,000 of each in the registered version of their program.) The free program gives you a good opportunity to try before you buy, and this is the benefit of most free programs.

There are online sites that list various free GPS software and describe how to use the programs after you download them. Often individuals who have used the programs themselves … Read More
