On the evening of the 18th of March 2021 Kevin Bolton on behalf of NavWorld presented a Satellite Navigation Talk to the Monument Toyota Constantia and Rivonia Toyota 4x4 enthusiasts at Hobby Park in Krugersdorp. Just after 19:00 Riaan Kotzee introduced Kevin and handed the floor to him.
Kevin Bolton is an experienced satellite navigation specialist starting his passion for the subject as far back as 1982 while still in the military. During his 43 years in this specialist field he has worked in South Africa, Turkey and a number of African countries, presenting talks and satellite navigation training courses to professionals and recreational enthusiasts. He has also visited Garmin Europe on three occasions to gain a better in-depth knowledge of their products.
The presentation started by reminding us of the basics of navigation:
Followed by the elements of navigation:
Once the introduction was over the basics of what Satellite Navigation can do for one while out in the unknown were discussed. The reason is that many people think that a GPS is a nice to have and not always necessary.
In today’s world there are four major GNSS in the world being, NAVSTARGPS the American system, GLONASS the Russian system, Galileo the European system and Beidou the Chinese system. At present Beidou is only reserved for military applications by China and Pakistan. If all four systems were available we would be able to receive signal from more than one hundred navigation satellites.
The next point that was discussed was how to select a Satellite Navigation System that you would wish to purchase. Breaking the crucial points into 6 headings. Listed below are just a few examples that would help guide you in making this selection.
It should be remembered that the top of the range might not always suit your needs and that you could get away with something cheaper.
The question was then asked can a cellphone do the same job as a dedicated Satellite Navigation Device. In Kevin’s opinion and his answer, a definite NO. A cellphone does not have the required battery life, most cellphones would not have the TrackLog capability, if it did it would use data for map downloads in most instances which could be costly and that is if there is network coverage. A cellphone is ideal for street and city navigation but not suited for the outdoor adventures and 4x4ing.
At this point he discussed the Garmin outdoor products that he would consider. To his knowledge Garmin is the only manufacturer that is still selling these outdoor products in South Africa, as all of the other top brands have either withdrawn from South Africa or have totally closed shop and their products are no longer supported or available in South Africa.
The Garmin products that he discussed was:
Next on the agenda for the evening was to give an insight into a few new Garmin products on the way:
Once finished with the product overview the different mapping that can be loaded to Garmin satellite navigation devices was discussed, being:
To complement the Garmin products possible accessories that could be of value and purchased additionally were discussed.
Some comments were made that people should take a bit of caution when using a satellite navigation devices.
In closing Kevin gave an introduction and a few tips when using the Garmin Base Camp program.
Base Camp is a map viewing or mini GIS, software package, intended for use with Garmin GPS navigation devices. It will organize, save and create data, plan your trip with common datasets that can be shared between friends. The software should be used to plan your next hiking, biking, motorcycling, driving or off-roading trip. You can view your maps, planned routes, and marked waypoints.
The planned 60 minute presentation stretched into a 2,5 hour session with numerous questions from the audience afterwards. In the end a most enjoyable and enlightening evening for everyone.
