Q: What are the tradeoffs between using L1-only and L1+L2 for PPP?
A: Precise point positioning (PPP) is a technique that can compute positions with a high accuracy anywhere on the globe using a single GNSS receiver. It relies on highly accurate satellite position and clock data that can be downloaded from the International GNSS Service (IGS) or obtained in real-time from a number of service providers, using either the Internet or satellite links.

August 1994, early morning. Spain’s Central Pyrenees Mountains still in darkness.
At the outset of an ascent to a 3,000-meter peak along the international border, one of the co-authors encounters a group of tourist hikers who have begun searching for a colleague who had left the camp the previous evening. In the pre-sunrise gloom, helicopters cannot yet operate.
A week later, the body of the hiker is found. The rescue efforts came, unfortunately, too late.

And then the fun began: the addition caused software handling Internet services such as LinkedIn, Pinterest, Mozilla, Reddit, StumbleUpon, Yelp, FourSquare and Gawker to behave unpredictably or even crash over the weekend.
