data transmission is more accurate than the phone’s own GPS system, according to research by the UK’s Department for Business, Innovation and Skills.
It is also cheaper.
According to the research by Oxford University, the cost of a GPS unit at the time of purchase is £1.35.
This compares with the £2.60 the phone charges to download a satellite navigation system.
The research also found that if you own both the smartphone and the satellite navigation, the device’s GPS system is more than twice as accurate as the GPS on the satellite.
“The best GPS is the one that’s free,” said Professor Stephen Jaffe, the lead researcher on the study, which was published in the British Journal of Navigation and Remote Sensing.
“You can’t get it from a company that charges you for it.”
He added that you should “absolutely” be using your smartphone as the primary GPS receiver.
“Your smartphone has been given the signal,” he said.
“And it’s the only way to see it.”
