The Global Positioning System (GPS) signals that we use for all manner of location, navigation and timing applications, emanate from a constellation of 24 satellites orbiting the earth some 12,500 miles above ground level.

GPS is a revolutionary piece of communications technology that provides us with the means to determine our exact location more or less anywhere on earth. It also provides a highly-accurate timing signal that is used to synchronise communications networks worldwide.

To ensure that a GPS repeater installation works properly, the system must satisfy certain requirements.The selection and correct installation of system components will make all the difference and ensure great results.

We occasionally get asked about the differences between GNSS and GPS.Is there a difference, or are they basically the same? Are they related terms? Do I need a GPS repeater or a GNSS repeater?This is a brief explanation of the relationship between GNSS and GPS.

Often, firefighting professionals encounter a serious problem with their GPS navigation systems when they leave their fire station in reaction to an emergency call out. Mobile Data Terminals (MDTs) and any other satellite navigation equipment present can fail to provide accurate directions to the incident. This can have serious, and potentially fatal, consequences.

Many fire stations encounter the issue of a lack of GPS coverage inside the building. This can result in unnecessary delays and longer callout times, as well as increased general confusion. Fortunately, the solution to the problem is relatively simple.

GPS disruption in police stations can be a cause of unnecessary confusion and delays in response times. Understanding why the issue happens and the most effective path to resolving it is essential.

Everyone knows that the police force in the UK is crucial to keeping us safe and reducing crime. As in all sectors now, the police use a variety of tech-based systems to help them in their role. One example is the hand-held portable radios officers use to communicate with. These police radios not only keep officers in touch with the control centre but also use GPS signals to identify where they are.

If your networks or systems use Coordinated Universal Time (UTC), April 6^th 2019 is probably a date worth marking in advance.

On, or possibly after, this date, some GPS receivers may start to behave strangely.  The data they output may jump backwards in time, resulting in month and year timestamps that are potentially up to 20 years out of date.This is a known issue; in April 2018 the Department of Homeland Security in the United States issued a memo to make GPS users aware of the situation.  Any changes, adjustments, or other actions are ultimately the responsibility of the user, so DHS strongly recommends owners and operators of critical infrastructure to prepare for the rollover.This refers to the GPS Week Rollover on Coordinated Universal Time (UTC) derived from GPS devices.
