How Satellites Have Changed My Hiking Life: A Look At Tech & Backpacking Part 1

Igloo Ed Huesers using a handheld GPS device in Yellowstone National Park in 2009

Working on the forthcoming republication of High Summer, the story of my walk the length of the Canadian Rockies in 1988, I’ve been struck by one huge difference between then and now, the rise of electronic and digital tech. Whilst all the backpacking clothing and equipment I used wouldn’t look too out of place now and its functions haven’t changed at all I now carry items that were the stuff of science fiction back then (which is appropriate as many of them require satellites in space to operate). I’ve written about this in general in a new introduction to the book but I thought it would be interesting to look at the timeline of the changes and how and when new items were added and the effect they had.

Satellites are the key to these changes, satellites for navigation and for communication. So they come first. This is the space age!

Satellite Navigation

Silva Multi Navigator

Magellan launched the first consumer Global Positioning System device that used a satellite array to calculate its location on the ground just a year after my walk and similar ones soon appeared during the 1990s. I tested a few for The Great Outdoors magazine. One of the earliest was the Silva Multi Navigator which I tried in 1995*. This was a bulky device weighing 227g that ran on 2 AA batteries. Like other GPS devices it gave your position in Lat/Lon or grid numbers which you could then find on a map. You could record tracks so you could retrace your route and it had an electronic compass and a barometer/altimeter. It sounds very basic now but seemed like magic at the time. You could stand on a featureless hillside in thick mist, press a button and a grid reference appeared. Plot that on the map and you knew where you were to within maybe ten metres. Amazing!

I wasn’t though convinced enough of the value of GPS devices to take one on my round of the Munros and Tops in 1996. With 512 summits to climb I wanted to keep the weight of my load down and decided GPS was something I could do without. In retrospect there were a couple of times it would have been useful but mostly it would have just sat in the pack.

SatMap

The next development was GPS mapping and a decade after using the Multi Navigator I was using a SatMap device with maps on it. Now I could see where I was without having to read the grid reference on a map. Amazing again and, I thought, much more useful.

My first smartphone in use on the Pacific Northwest Trail in 2010

In 2007 Apple launched the iPhone and the smartphone revolution began. I could immediately see the advantages of these tiny computers for long-distance walks. They could take pictures, carry books to read, show your position on a map, link to the internet, and even be used for phone calls. In 2010 I bought one, the HTC Desire, and took it on the Pacific Northwest Trail with all the maps downloaded on to it. Long before I finished the trail I was hooked. I’ve never been backpacking without a smartphone since. I’ve never carried a standalone GPS device again either. There seems no need. I do still carry printed maps though. I like the overview a big map sheet gives and anyway I think I’d feel underequipped without one plus a magnetic compass. Twenty-five plus years of using them on hundreds of days has left the need for them ingrained. I do virtually all my navigation with the smartphone however.

For communication with the outside world the first smartphones were only useful when there was a signal though, which was hardly ever in wild places. On the Pacific Northwest Trail I was just as out of touch most of the time as I had been on earlier walks. I was just less likely to get lost, which would have made a huge difference on the Canadian Rockies walk where I spent around a week somewhat unsure of my whereabouts. That part of the walk would have been unrecognisable if I’d had GPS mapping.

Satellite Communication

SPOT & Garmin InReach

With satellite navigation established satellite communication soon followed and being in touch without a phone signal became possible. I’ve been using a GPS** satellite communicator the last thirteen years (I was surprised to discover it was so long but my first gear list with one is dated January 2011). Until two years ago this was a SPOT unit which I just used to send an ‘I’m OK’ message from camp each evening. It had no screen so ironically it didn’t show my position, though it did to the recipients of the message. Still, I had my smartphone to show where I was in case I didn’t know.

It wasn’t long before satellite communicators with screens and two-way messaging became available. I was happy enough with the basic SPOT for a while but then I was sent a Garmin InReach Mini 2 to test in 2022. As with my first smartphone I was quickly hooked. Especially as it linked with my phone so I could use its much bigger screen for sending and reading texts and emails. I still send the basic OK message each day but when needed I send more info such as when I expect to finish a walk and I can also receive messages and news from home.You can read my full review of the InReach Mini 2 here.

Satellite communicators are key safety devices of course and can be used to call for help just by pressing a button. I’ve never had to do this and obviously hope I never will but having it is a reassurance, as much to my family as to me, as is being able to let them know I’m OK every day. Before this was possible they were used to me disappearing for weeks at a time but now I suspect they’d think that irresponsible.

GPS has changed navigation and communication in the outdoors greatly, making the first much easier and the second possible. Whether this is good or bad or a mix of both is another matter. Whatever anyone thinks the change has happened.

There are other electronic and tech devices that didn’t exist for the first half of my backpacking life too – e-readers, weather trackers, portable battery packs. I’ll go into these and what they added to my backpacking in terms of utility and weight (or reduction in it) in Part Two of these all-things techy posts.

*I can’t remember all the dates I started using stuff of course. I consult a Word document containing lists of the gear I’ve used on just about every overnight or longer trip since 1993. It now runs to 490 pages! Luckily Word’s search engine works well.

** Now there are several global navigation satellite systems they should correctly be referred to as GNSS. However GPS was first and is established as the generic term so I’ve stuck with that.
