How to use QZSS on S9B

[Luís Pinto]

@Takeshi-Kakeda try to use GPS Test APP to see systems on your country and sats if your smartphone have a chipset to support all constellations: https://github.com/barbeau/gpstest

You just have two regional systems QZSS (Japan) integrated on American system and IRNSS (Índia) not integrated. Índia plan to do a global system in future. GB after brexit also have plans to do their own system.

You should be able to see in app for example this:

Hi what @Luís-Pinto said.

Qzss is enabled always on all S series watches

You don’t need Todo anything about it and it doesn’t consume any extra battery

Because QZSS is designed to improve GPS, while the other systems (in theory) could be complete replacement.

[Luís Pinto]

@isazi QZSS is a regional system in Japan and others are global, and yes can be work without Navstar.

I’ve be testing galileo (just) with smarphone with a external antenna and a specific app from that brand that allows to choose a constellation and results are amazing (both static and moving, without dual frequency - my phone don’t have that possibility), better than nav+gal! But in my zone, in Asia can be worst. Next will test bds.

@Luís-Pinto how ? (Do you test) eager to learn

List of products that support the Quasi-Zenith Satellite System (QZSS)

Suunto has only one device listed , Suunto7

@Dimitrios-Kanellopoulos it’s a APP included when you buy a external antenna. This antenna, is connected via ble. You can select constelation that you want, or select dual/triple constellations. Later can inform details: https://geospatial.trimble.com/products-and-solutions/trimble-r1

Even u-blox antennas there is software to choose systems and single or dualfrequency:

@zhang965 S5 and S9 have QZSS.

[zhang965]

@Luís-Pinto
Yes, I know S9 has the QZSS,

But i just don’t think it can work only with the Gps
Option, and GZSS will be a complete system as well.

that is a bit outdated list. Vantage has also QZSS and others.

Yes vantage is in the list so does suunto7

[Dimitrios Kanellopoulos]

@zhang965 ok

[Dimitrios Kanellopoulos]

Again to make it clear for the OP the QZSS is always on

For the specs of the watch see details on Suunto .com https://www.suunto.com/en-gb/Products/sports-watches/suunto-9-baro/suunto-9-baro-black/

[isazi]

@Luís-Pinto alright, but with 4 satellites it is not global.
I just read they’re planning to extend it to make it standalone, but it’s future work.

[Luís Pinto]

@isazi i Said before qzss is regional.

Hi, thanks for all comments.

Wao! it’s so wonderful for me.
I wondered if S9B specs told possibility of QZSS, but I couldn’t use it
So I can tell my friends that suunto S series watches support QZSS like garmin watches .

[Dimitrios Kanellopoulos]

@Takeshi-Kakeda yes sir

[Takeshi Kakeda]

@Luís-Pinto said in How to use QZSS on S9B:

@Takeshi-Kakeda QZSS is integrated on Navstar system. You don’t have to do anything to use regional Japan system. It means that if you use Navstar alone (GPS) is nav+QZSS, if you use nav+gal you real use in Japan Nav+QZSS+Gal.

Thank you for your detailed comment.
I have grasped what QZSS is.
Ok, I’ll try gpstest to know how the system does .
