TrekBuddy

[Hual]

Hello

I am very new in this forum, and also with trekbuddy and my new nokia5800.

First i want to say thank you to the builders of trekbuddy and additional features!!!!!!!!!

I am a very enthusiastic paragliding pilot, and i want to use my nokia as a backup-gps.
I use also a garmin etrex-vista.

I try now to make a cms for the noka 5800 for paragliders.
Paragliders need a very simple cms with following contains:

-time
-altitude
-vertical speed (positiv or negativ) in meters/second
-gliding ratio (=groundspeed divided by vertical speed)
-groundspeed (very very important!)
- needed ratio to next waypoint
- direction to next waypoint (a little compass-needle)
-distance to next waypoint
-distance to last waypoint
-dinstance to first (start) waypoint


usefull but not very important:

-values of built-in accelerometer
-oters? (do other pilots have any needs?)

cms should have a very good readability in sunlight!

What i am also looking for, is a simple map, on which i can see som towns/villages an airspaces (i need switzerland an europe).
Airspaces should also show the important informations such as:

-radio frequencies
-tma or ctr (kind of airspace)
-max. or min. hight (geographical infos)

there are some maps here:

http://www.dfc-saar.de/

or for google-earth:

http://www.skyfool.de/2009/04/01/neue-luftraume-fur-2009/


Are here in this forum other pilots with similar requirements?

Does somebody have some good ideas for me?

Thanks

I am a paraglider pilot, too.
I am looking for something similar, and I found a good starting point in the latest 9-view CMS from MaleSmurf. I am thinking of modyfying it to fit our requirements, but I still have to study how to use the very new scripts.
I am using a Nokia N95 (240x320) at the moment, so probably if the resolution of your display is different you will have to adaapt it. Anyway, I will tell you all as soon as I have some time to do it.

Here is a map...
loading via "load atlas"->atlas.tar

switching between osm and airspace via key "7"

Hi,

I have transformed simple CMS by marc (from this thread http://www.trekbuddy.net/forum/viewtopic.php?t=693&postdays=0&postorder=asc&start=15 ). I have SonyEricsson P1i (320x240 px screen) with HGE-100 GPS handsfree.

My CMS has these areas:
[list=]sat/fix
speed
course
altitude
vario (vertical speed)
time
duration (of moving)
distance from waypoint (personally I use it as distance from takeoff)[/list]
and 2 new features implemented with the help of HECL:
[list=]graphic vario (similar to Flytec 4005 etc.)
glide ratio[/list]

My CMS is very simple, no special graphic, only values, small symbols and units, placed on the screen in the way I found usefull. I am XC pilot, no competitions, therefore there is no need to have "glide to waypoint" or "course to waypoint". But I agree they are important in competition flying.

According to my experience, "variometer" based on GPS is suprisingly precise - this flight http://www.xcontest.org/cesko/prelety/detail:scorpi/21.3.2009/12:24 was done only with the help of trekbuddy with my CMS (I forgot all the instruments inc. vario and Garmin GPS at home:) and I think it is very good backup for thermalling - the only disadvantage is that you must look on the screen continually....but it depends on the GPS unit - my personal experience with SE P1i / HGE-100 are very good.

Visibility on the sun - very good in daily mode with white background and black foreground. This flight http://www.xcontest.org/cesko/prelety/detail:scorpi/31.3.2009/11:42 I tried Trekbuddy with my CMS together with Garmin Legend and Flytec 4005 - and I must say that:
1) detection of thermals (up/down) was very similar to Flytec
2) height difference against Garmin Legend was no more than 5 meters within 3 hrs flight.
3) at the end of the flight the battery was down (mainly because of constant backlight I guess - of course, it was very cold over 2000 m).

Glide ratio is not yet ready, seems buggy in this moment, but the idea is simple - it is measured as value "integrated" by 10 seconds.

Now I must wait for lat/lon implementation into HECL, I have some ideas how to extend it for XC flying...

[gdpno69]

Hi pilots.
I tried to create a first version of the CMS I wanted, but with no full success: I realized there was no wpt information available in the scripts, so I could not add glide ratio to waypoint.
Download the CMS from Malesmurf, backup, and replace the files in the zip.
I have big fonts, and only what I need:
-time and sat view
-ground speed and vertical speed
-compass
-current altitude and current glide ratio
-compass to WPT
-WPT altitude and WPT glide ratio (now always 0.0 )
-WPT ground distance, arrow to WPT, and WPT name

No filters are implemented, so real time information is always displayed, but fluctuations may be big (with my internal receiver).

Let me know if it can be of any help to you too.

Hy thomas, hy gdpno69

very nice, an your work works! Thank you!
Now, this is a atlas, so it should be zooable? But you only put one layer in it, so I can't zoom, is that right?

On my 5800 with big screen it looks quiet comfortable!


I need "distance to start-point" for i know how many kilometers ife already done.

I know that these simple phone-gps values are all very unprecise. I use them only as packup, an it ist a nice to have. I mean this also for gliding-ratio and gliding-ratio to waypoint

My real interessts ar in the airspace-maps!

cheers

Hi,

I am working successfully on my own cms. A very simple one.
It would be fine, to see both altitudes, those in m and those in feet.
For flying i use m, for talking to airports, I need feet.

Does anybody has a solution?

So,

for the first time in my life, i did the xml-programming, an it works!

See my file and give your coments (and help) please.

Hula



I see, i have some problems to make a zip attachment, it says, my zip-file is to large (27KB!).
xml files are not allowed, so I renamed it to a *.txt file........

And also this file is to large (4KB), so I have to add it as text!!!!!!!!

Perhaps somebody can help me with attachments????????????

Hi Hual or Hula
when you set trekbuddy to metric following line should give feets:

<area x="325" y="70" w="200" h="50" font="60px" align="left">
<script>print [* $cms::alt 3.28084]</script>
</area>

if you want to talk to Nasa, following line should give the Flightlevel:

<area x="325" y="70" w="200" h="50" font="60px" align="left">
<script>print [* $cms::alt 0.0328084]</script>
</area>


not testet.

Thomas.

[Hual]

Hi thomas,

I have tested it now, it doesn't work.
I modified the comand by this {}, because i thougt you forgot it, but it wasn't the fault.
See here:

<area x="325" y="146" w="200" h="50" font="48px" align="left">
<script>print [* $cms::{alt} 0.0328084]</script>
</area>


The fault must be somewhere else.........

but thank you!

I have a 5800 XM

does this mean we now have someone creating cms for this phone??

[gdpno69]

[thomast]

[Hual]

Hi,

did anybody test my cms for nokia 5800xm?

Thomas helped me to convert meters into feet. It doesn't work on my 5800, but on his phone it works. Has anybody a solution for the problem.
Thomas sent me a little test-cms. Feet are only set at "0", meters are working.........

Hi all

I'm a french paraglider pilot and a happy 5800xm owner.
I discovered trekbuddy last night and it looks like THE best flying soft for me.
I've installed it with no problem. But i've some question and i can't find solution in da forum... I've downloaded CMS PGv01.zip but what must i do with it to pimp my trekbuddy? Sorry i'm not an computer expert...
I hope PGv02 is still in dev because i think it'll be perfect !

THx in advance and for the great job

Nico
