Over the last few years, we have seen different technology labels from different GPS and mobile device makers. InstantSIRF Fix, Enhanced GPS, aGPS, are essentially the same, or commonly known as Asssisted GPS (or AGPS). The technology has been introduced in the market for a few years, but it continues to confuse alot of people, thinking that it’s another variant of LBS (location-based service). When HP first introduced built-in GPS in their flagship iPAQ product, iPAQ 6515, it has not received much attention other than it’s just a phone with some GPS chipset. HP had not marketed the benefit of A-GPS then. Neither were the reviewers, who probably don’t understood the purpose of A-GPS, judging by the number of reviewed articles on this topic.
