Currently I am the Founder/owner of Heedra Limited. A UK based Consultancy/VAR in the Satellite PNT area. I am also a Director of Accucom Limited, a UK Navigation Technology Development Company.Heedra was formed in 2016, but my personal experience in GPS/GNSS dates back to 1987, this was when I first started working on GPS test equipment at STC. This project eventually became the Spirent GNSS Simulator System.Heedra can help companies understand GPS/GNSS and in particular how to Test GPS/GNSS devices. It has it's own GPS/GNSS test systems and can perform testing for other companies as required.Heedra also markets products of other companies to the UK/Ireland Market Including GPSatSystems who are an Australian company specialising in GPS/GNSS Interference detection equipment.GPS/GNSS testing is a complex subject. With many companies offering simulation equipment, that can vary tremendously in price. Heedra can help you to understand the differences in signal quality and modelling capabilities between the various test systems. Heedra can also help you to understand the different test requirements, what is necessary for your testing, and which is the best equipment to use for this.For over 29 years of my career I worked on the Spirent GPS/GNSS Simulator project, I am very proud to have been part of this Product, working as an Engineer in Development (between 1987 and 1997). Then supporting Sales between 1997 and 2001, finally from 2001-2016 I was privileged to be involved in the Sales of the Spirent Simulators across APAC and the UK. At the end of 2016 I retired from Spirent.
