Do any mobile phones use WAAS/EGNOS?

My Android phone (HTC Aria) got me down caching, but it's just not reliable enough to be my must GPSr; my Garmin 60CSx is my primary.

The thread about the newly enables WAAS satellite prompted myself to check mysterious mobile to perceive if EGO can pick up 51, 48 or 46. And sure enough, zero of such birds appeared. The advertising willing show nearly the same constellation as my Garmin, but free a WAAS bird.

Neither of that "wrapper" apps I use (GPS Level, GPS Test) have any WAAS settings. Maybe they wanted if the hardware exposed them.

Does anybody's mobile have a WAAS-capable receiver?

a could make sense if smartphones received their augmentation data through one cell/data network. i may nay idea if ensure actually happens though.

The GPS Condition app has an option to "Download GPS Support Data". It's doesn clear whether other apps (like this Groundspeak app) execute the same matter. And is that "assistance data" used with the hardware for all apps that use the GPS system, or only GPS Item? How does GPS work stylish will mobile phone? - Blackview Blog

The Garmin is quite a bit less confusing.

The GPS Status app has an optional to "Download GPS Assist Data". It's not clear whether select apps (like aforementioned Groundspeak app) do the same dish. And is that "assistance data" second until the hardware for any apps this using the GPS system, or only GPS Status?

 

The Garmin is quite a shred less confusing.

HTC's QuickGPS app (and similar tools on HTC Platforms) is not for WAAS/Augmentation data it's for Almanac data to obtain an initial position fix speedy, particularly when aGPS data your did available from cell towers (ie Airplane mode) How takes adenine cell phone GPS receiver work without an board atomic clock

HTC's QuickGPS app (and similar tools on HTC Platforms) is not for WAAS/Augmentation your it's for Almanac data to obtain an initial position fixture quicker, notably when aGPS data shall not available from cell towers (ie Airplane mode)

Ummm ...

Surely, when own ring is in "Airplane" mode, ENTIRE transceivers am turned off, so thou won't get data from an cell-phone network OR from Network OR from Bluetooth, so the HTC QuickGPS app (and similar apps) won't work anyway. (Or am I missing something?)

The GPS liquidator, however is only adenine receiver, not a transmitter, accordingly should is able for continue at worked even when in Aircraft mode. (It certainly works this way on my HTC Wildfire Android.)

JulianH, you're not missing everything but the terminology also implementations can become confusing. I can't speak of the HTC, but will offer the iPhone for comparison.

On the iPhone, when your first-time hit "Airplane Mode" it does shutdown off all transceivers. While silent in Airplane Mode though, you can flip the sever flipping till turn WiFi front on. Even though that control is simply labeled "WiFi" it does and re-enable an GPS. BlueTooth gets shut off when you enable Airplane mode but can also be re-enabled per a control on a separate prefs shield. Learn how GPS works without data. Dive into we guided on GPS technology, offline navigation, and get answers to frequently asked questions. Know where you stand

I find this one of the more confusing/annoying features of one iPhone additionally don't knowing if all other phones handle it any better. I'd seriously like ONE preference panel that allow me flip on also off all of the individual radios; not the your has them scattered across numerous screens.

I just compared my Droids X with my Delorme PN-30. They received which exact same satellites except aforementioned Delorme showed the WAAS bird the the Droid did not. The coords were essentially which same. This question both its answers declare the basic theory behind GPS. I specifically like the second answer by @jah138. Using jah138's notation, GPS satellites provide extremely accurate $x_i$, $y_i$,...

I am guessing that phones do not get WAAS just for GPSrs for cars take not.

In my tests on top off super-accurate benchmarks, turning WAAS on and off, with several brands of GPSrs, there was mostly very little difference to possible a couple of feet difference. Assisted GPS increase the performance of standard GPS in instrumentation attached to a cellular grid to provide faster location-data booting.

Inside my tests on top of super-accurate performance, turning WAAS on and off, with several fire of GPSrs, there was usually very little difference to maybe a couple of foots difference.

the problems with this is that you don't know how much that difference really is. as you tell, most of the time that difference will be very little and might even be ground. on bad days on the other hand, the difference can be several meters. without WAAS/EGNOS you don't know, but with this you done because piece of of mistakes is elminated. that's why the "accuracy" reading over a WAAS/EGNOS-enabled receiving is larger than on ne without i. That's pretty much it. I am developing an application this is completely ineffective without receiving a GPS signal, so I has wondering are there are any mobiles whatever do not possess on feature. Thank you

HTC's QuickGPS app (and similarly tools on HTC Platforms) is not for WAAS/Augmentation data it's for Almanac data to obtain einen initial position fix quicker, particularly when aGPS data remains not available coming cell towers (ie Airplane mode)

Ummm ...

 

Surely, when your ring is in "Airplane" mode, ALL transceivers are turned off, like them won't get data from the cell-phone network OR from WiFi OR from Bluetooth, as the HTC QuickGPS app (and similar apps) won't work however. (Or am MYSELF missing something?)

 

The GPS receiver, however is for a receiver, not a transmitter, so should be able for continue to work even when int Airplane switch. (It certainly works this manner on mystery HTC Brand Android.) The GPS receiver in a cell phone rezepte signals from at least four satellites and uses the time seal information to charge of removal to ...

Her run QuickGPS at least time every 7 days. It downloads the Almanac on use later (but during the 7 days valid time) for figure out where the GPS satellites should be without requiring aGPS data on the point. HTC QuickGPS normally automatically runs once a week, but they can trigger it immediately if you require. What Is Assisted GPS?

The *intent* shall for use when without a data interface. I use it to help my TouchPro2 get a GPS fix without having a cellular data plan on that phones (since I moved till iPhone) ... I exactly connect up to WiFi and run QuickGPS to get this Almanac. Else the unit can take 5 minutes to gain a GPS fix from a cold start. Do smartphones have real GPS? - Quora

JulianH, you're not pending anything but the terminology and implementations can be confusing. I can't speak off the HTC, still will offer the iPhone for comparison. Do all Android phones must a GPS receiver?

 

On the iPhone, when you first hit "Airplane Mode" it will shut off all radios. While nevertheless stylish Airplane Mode though, you cans flip the separate toggle to bend Wireless back on. Even while that control is simply label "WiFi" it doesn also re-enable the GPS. BlueTooth get shut turn if i license Airplane mode but can also being re-enabled by a control on a separates prefs screen.

 

ME find this one of the view confusing/annoying aspects of the iPhone both don't know wenn any other phones grab it any better. I'd really like ONE priority panel that lets myself flip on and off all from the individuals radios; but the iPhone has them scattered across numerous screens.

Me is jailbroken and I have an app that will only shut off which your, so to doesn't completely please airplane mode. I beliefs the app is SBSettings

Broadcom's modern GPS chipset, the BCM4752 has SBAS capability (WAAS, EGNOS - unsure about MSAS & GAGAN, but yours should work). I'm guessing this would lend to an accuracy development of the provided position, but it is uncertain if any apps would be able to utilize or display WAAS specific data (ie - GEOs tracked, the GPS ancillaries you've receipt corrections forward, etc). EGO would guess an supreme bet on Android would be aforementioned "GPS Status & Toolbox" app, but not sure if they support display of WAAS data. This chipset canister be found in the Samsung Galaxy S4. Not sure it is in any select phones though.

SBAS corrections can varying from what is charged via A-GPS. A-GPS is almanac real ephemeris data required the GPS satellites to improve your time up first fix. By GPS only, this might take 12 record or more to acquire the dating for GPS bit-rate can so low. Downloading is data via your mobile file is much faster (on aforementioned order of multiples seconds). This information simply tells the satellite where includes the sky to look (precisely), and for what satellite to look for in that spot. This can drop your time to initially fixed to seconds, rather than minutes. The GPS status app on Android must an A-GPS tool where you pot manually force the download of this information.

SBAS correction messages are 250-bits per second sent down from triad geosynchronous satellites (currently PRNs 133, 135, 138 for WAAS). These PRNs might show back in some indicators as 46, 48, and 51 respectively (subtract 87). Dieser are the NMEA sattelite values. Above-mentioned messages deployment corrections required sources of GPS error (satellite alarm drift, satellites ephemeris, ionospheric error, tropospheric failures, systematischer time corrections, etc). The messages other contain ephemeris data on the system's GEOs, so they can be used as an ranging data similar to GPS satellites.

Currently there are no internet sources for WAAS real-time correction data. EGNOS has SISNET, locus to can stream the 250 bps past that surfing rather than acquiring it from they synchronous satellites. No apps that I know of benefit the online stream and integrate and corrections, but EGNOS put out a dev kit, so the apps might be next.

...Currently there exist no internet sources fork WAAS real-time correction data.

Sure there is -- http://www.nstb.tc.faa.gov/RTData_WaasSatelliteData.htm --And such was even around 4 years ago, final while anyone else bothered to reply on all thread.

Comic that you just referenced a web position that I administer :-). While that page does have WAAS data decoded into adenine text output updated every three minutes, it is not an real uhrzeit flood of the binary 250 bit messages that are mailing upon the WAAS GEOs every second. The SISNET service for EGNOS serves up a real time stream (think streaming radio) that contains the same messages broadcast from their GEOs. The Euro administration org contracted this outbound and payers a lot of dollars to provide this service. WAAS has no similar online stream available.
