These incredibly useful devices are now used by the general public, and have high availability. Most modern vehicles use Satellite Navigation systems, and it is the information in these systems that can give assistance in providing information to others, (be they law enforcement officers, defence lawyers, employers or members of the public). Most Satellite Navigation systems have logs and configuration files that need to be examined and broken down into readable and understandable information. The Satellite Navigation system has both hardware coding written to itself and software. Examination and interpretation of this software enables us to find waypoints, (predominantly on Marine Satellite Navigation systems), and directions requested on vehicle Satellite Navigation systems along with directions given and times that the journey was taken. This type of information is often satisfactory to a judge when charging an accused person of either guilt or innocence of a crime.

Obvious benefits of the service of an examination of Sat Nav, or Sat Nav Forensics are law enforcement officers, prosecutors, defence lawyers, employers and members of the public:

Law Enforcement Officers - The police, or other law enforcement agencies may be able to exactly pinpoint the position of an accused person if that person used a Satellite Navigation system. If an accused person states that he was in one place, but his car Satellite Navigation system states that at the time that the vehicle was 200 miles away, the information given adds to the intelligence that the law enforcement agency has against the accused, or is even enough to charge the said accused person.

Prosecutors - The prosecutors often work alongside the law enforcement agencies, and as such will use the information gained in Satellite Navigation forensics in the same way.

Defence Lawyers - Defence lawyers are there to examine any and all evidence and try and pick flaws in it. If a law enforcement agency has not yet examined the Satellite Navigation system, the evidence produced may well be enough to have the accused proved innocent or cast doubt over his guilt. It is this reason that the more and more defence lawyers are turning to Satellite Navigation Forensics.

Employers - Subject to the company handbook, the employees contract, and the company acceptable usage policy, (AUP), the employer may have the right to examine the Satellite Navigation systems of its mobile employees. This service is being used as employees want to know that their staff are indeed using their working hours efficiently. They may also use this service if they believe that the employee is not being as honest with their work details as they perhaps should.

Members of the Public - In rare instances, a parent may want to check that a child has been where the child states they are going. There may be a history of drug abuse, of unsafe relationships, and using the Satellite Navigation system in their car, they would be able to get a true idea of whether or not the person in question has indeed been where they said they had. The same is true of a husband who suspects that his wife or partner is having an affair. It may seem that this service is taking a rather Big Brother approach, but if the relationship is about to fail, there is often hundreds of thousands of pounds at stake. This evidence would be used by a judge to associate blame to one party, and therefore a larger percentage of the partnership equity may be give to the 'innocent' partner.
