Today I am beginning a multi-part blog series on the design and development of a location-based Windows* Store app. My goal is to provide developers with a complete, real-world example of creating a location-aware application on the ultrabook and tablet platforms. While an internet search will tu...
Buggy Geolocation drivers, Part 2: Calculating speed when your driver doesn't
Par John Mechalas (Intel) Publié le 05/02/13 0
A couple of days ago I talked about my experiences with a geolocation driver bug that was not presenting a heading to the Geolocation sensor, and how to account for this problem in your app by calculating the value yourself. Today, I want to talk about a very similar problem I have encountered wi...
Buggy Geolocator drivers: How to calculate Heading when your driver doesn't
Par John Mechalas (Intel) Publié le 31/01/13 1
I've been evaluating the location sensors in a number of Windows 8 tablet and ultrabook systems recently, and as you might expect I have come across the occasional buggy driver. Sometimes the bugs are severe enough that the location sensor doesn't function reliably or even function at all, but I ...

No GPS? No problem! Using GPSDirect to develop location-aware apps (Part 1)
Par John Mechalas (Intel) Publié le 13/12/12 4
In an earlier blog post titled "Develop location-aware, Metro style apps when your development system doesn’t have GPS", one option I presented for those wishing to develop high-precision location-based Windows Store apps is to hook up an external GPS to your computer. What I want to do now is ex...
Does the target system have GPS/GNSS?
Par John Mechalas (Intel) Publié le 10/12/12 0
Recently one of my colleagues interviewed me in a short video segment on the geolocation sensor in Windows 8, and one of the questions I was asked was whether there was an app that could tell the developer or the user if their system has a GPS or GNSS receiver in it. The direct answer to this que...
Calculating a bearing between points in location-aware apps
Par John Mechalas (Intel) Publié le 30/11/12 1
Earlier this week I wrote about how to calculate the distance between two points in a location-aware app. Today, I am going to discuss a related topic: how to calculate the bearing between two points. Like the shortest-distance problem, the bearing between two points on the globe is calculated us...
