| Sat-nav feels like state-of-the-art technology, but it's a century since the first auto-navigation device was invented and, says Joe Moran, there are fears such systems are starting to erode local knowledge. | |
| A report presented recently to the US Congress warned that sat-nav - satellite navigation - systems could start to fail from next year as the US Air Force's satellites deteriorate. It is yet another episode in our long and fraught relationship with in-car navigation - a phenomenon that is more ancient than you might think. | A report presented recently to the US Congress warned that sat-nav - satellite navigation - systems could start to fail from next year as the US Air Force's satellites deteriorate.

| Today's sat-navs are really a number of older inventions cobbled together. In fact, mechanical in-car navigation stretches back further than most people would think - 100 years to be precise. | Today's sat-navs are really a number of older inventions cobbled together.

| The earliest in-car navigation system was the Jones Live-Map, patented as early as 1909. It was a turntable with a pointer on which the driver placed paper disks for individual routes and it measured distance and direction through a cable connected to the front wheels. On early boneshaker cars and bumpy roads, with no opportunity for mid-course corrections, it must have been next to useless. | The earliest in-car navigation system was the Jones Live-Map, patented as early as 1909.

| If the Jones Live-Map had raised expectations among those seeking a reliable resolution to the in-car tensions between harassed driver and hapless navigator, they were to be disappointed. Over the next few decades, car manufacturers experimented with various Heath Robinson-like contraptions to guide drivers, some of which even promised to warn them about road conditions, like rough surfaces and police speed traps. But all of them were basically variations on the Jones-Live Map and about as accurate in giving directions. | If the Jones Live-Map had raised expectations among those seeking a reliable resolution to the in-car tensions between harassed driver and hapless navigator, they were to be disappointed.

| The Gyrocator was the first computerised in-car navigation system. Developed in Japan, it was like the Jones Live-Map - a solid-state system that could not respond to the changing narrative of the drive. So if you went wrong the errors soon stacked up and, unlike a broken watch, it would not even be right some of the time. | The Gyrocator was the first computerised in-car navigation system.

| However, unbeknown to most motorists, the technology for a real-time system already existed. The US Defense Department had developed GPS (global positioning by satellite) in response to the Soviet launch of Sputnik in 1957, but it wasn't until the 1980s that President Reagan made it available for civilian use. | However, unbeknown to most motorists, the technology for a real-time system already existed.

| The other technological piece of the sat-nav jigsaw was digital mapping, which was pioneered by a tiny British firm, NextBase, which grew out of a circle of friends who met as teenagers, programming some of the earliest home PCs at a school holiday computer camp in Northampton. | The other technological piece of the sat-nav jigsaw was digital mapping, which was pioneered by a tiny British firm, NextBase, which grew out of a circle of friends who met as teenagers, programming some of the earliest home PCs at a school holiday computer camp in Northampton. |

| The technology for sat-nav, in other words, was around for several years before it was developed. All these different inventions simply needed to be brought together. | The technology for sat-nav, in other words, was around for several years before it was developed.

| This suggests that the growth of sat-nav is not just about the advance of technology. It speaks to our contemporary anxieties and preoccupations about the road. More roads and better cars mean we can travel further, and so the risk of getting lost is all the greater. | This suggests that the growth of sat-nav is not just about the advance of technology.

| Britain's roads are also an increasingly bewildering place to navigate - a maze of spaghetti junctions, elevated roundabouts and coned-off contraflows. | Britain's roads are also an increasingly bewildering place to navigate - a maze of spaghetti junctions, elevated roundabouts and coned-off contraflows. |

| The British road system is no longer known by its epic cross-country routes - the M1, when it opened 50 years ago, was known as "the London-Yorkshire motorway". It is known by its pinch-points like Staples Corner (at the very southern end) and the Lofthouse interchange (where the M1 meets the M62), mentioned daily on radio traffic reports as vortices from which none can escape. | The British road system is no longer known by its epic cross-country routes - the M1, when it opened 50 years ago, was known as "the London-Yorkshire motorway".

| The motorways that once carried hopes of uniting the nation now evoke images of eternal circularity, encapsulated in those urban myths about foreign tourists (or confused pensioners, or naive northerners) who drive round the M25 for days in the mistaken belief that it is the M1. | The motorways that once carried hopes of uniting the nation now evoke images of eternal circularity, encapsulated in those urban myths about foreign tourists (or confused pensioners, or naive northerners) who drive round the M25 for days in the mistaken belief that it is the M1. |
| Sat-nav clearly suits an era which has given up on understanding the roads as a coherent, logical system - an era in which map-reading may be going the way of obsolete skills like calligraphy and roof-thatching. | Sat-nav clearly suits an era which has given up on understanding the roads as a coherent, logical system - an era in which map-reading may be going the way of obsolete skills like calligraphy and roof-thatching. |
| Perhaps that is why sat-nav devices are branded things like Road Angel and Time Traveller, presenting themselves not as scientific cartographers, but as magicians and soothsayers, guiding you through the maze of our road system by psychic intuition. Sat-nav is a seductive mixture of science and mystery, perfectly attuned to anyone unlucky enough to find themselves in the maddening twists and turns of the British road system. | Perhaps that is why sat-nav devices are branded things like Road Angel and Time Traveller, presenting themselves not as scientific cartographers, but as magicians and soothsayers, guiding you through the maze of our road system by psychic intuition.

| However, sat-nav still seems to make us uneasy. Many drivers, for example, dislike the voice prompts that say "take the first left" or "take the second exit". Most speech synthesisers use female voices because they are easier to distinguish from engine noise and road rumble - and British sat-navs have rather clipped, head-girlish accents. | However, sat-nav still seems to make us uneasy.

| Two of the early sat-nav voices were Susan Skipper, who appeared as Nigel Havers' posh girlfriend in the 1980s sitcom Don't Wait Up; and Eve Karpf, who voice-dubbed the famous line in the Ferrero Rocher commercial ("Monsieur, with these Rocher, you're really spoiling us"). | Two of the early sat-nav voices were Susan Skipper, who appeared as Nigel Havers' posh girlfriend in the 1980s sitcom Don't Wait Up; and Eve Karpf, who voice-dubbed the famous line in the Ferrero Rocher commercial ("Monsieur, with these Rocher, you're really spoiling us"). |

| Men in particular seem to recoil from being given digital instructions, and read the satnav woman's pregnant pauses, or her curt phrases like "make a legal U-turn" and "recalculating the route", as stubborn or bossy. Of course, they are reading too much into it. Sat-nav is just a dumb computer, obeying its algorithms. | Men in particular seem to recoil from being given digital instructions, and read the satnav woman's pregnant pauses, or her curt phrases like "make a legal U-turn" and "recalculating the route", as stubborn or bossy.

| We still don't quite trust the electronic voice to get us where we want to go. Since before even the arrival of the car, people have worried that maps sever us from real places, render the world untouchable, reduce it to a bare outline of Cartesian lines and intersections. Sat-nav feeds into this long-held fear that the cold-blooded modern world is destroying local knowledge, that roads no longer lead to real places but around and through them. | We still don't quite trust the electronic voice to get us where we want to go.

| You can sense it in all those fearful newspaper headlines about motorists guided by their sat-navs to the edges of cliffs or deposited in village ponds. We may have grown to rely on in-car navigation, but it will be a long while before we learn to love it. | You can sense it in all those fearful newspaper headlines about motorists guided by their sat-navs to the edges of cliffs or deposited in village ponds.
