Closing Comments on BriteNav and Vertica V2

Well I guess a final update has been long overdue -

My suggestions to Lawrence at Vertica were to work on getting a filter-free GPS engine motherboard, combine it with the BriteNav display I was using and call it Vertica V2. This is what you are now enjoying.

Lawrence had done most of the work working with our supplier getting the Vertica V1 revamped and in the end I didnt have the time to support the folks I would have sold the device to - Our supplier was getting many different folks in soaring pregnant with the idea of the V2 once we had solved the problems, (in particular Paulo at LK8000 did a lot of work on this.), so I decided this wasn't a situation I wanted to deal with - plenty of other guys ready to step in without respecting the original work of others.

No regrets - I have a few BriteNav prototypes to work with in the meantime....

Next will be an Android sunreadable display platform (like the Kyobe Reader) though sadly the Mirasol display may take a while to appear due to Qualcomms change in strategy. PixelQi has products in production but nothing in the sub7" screen size we need for cockpit use. Eink has  a prototype sunlight readable android phone shown earlier this year - and they have colour technology as well.

In the end we are at the mercy of enough 'ordinary' consumers wanting sunlight readability in their android devices - and longer battery life - until these are mainstream we will have to use solutions that are expensive, or power hungry , or both.

Too Little Interest - Whats Next??


Dear all

Thanks for those who got back to me after my last group update where I informed everyone of the Oudie announcement using the same screen as the BritNav.

There are 2 issues I am still trying to resolve.

Firstly, in the 2 weeks or so since my last update I’ve been waiting for interest to be confirmed and to firm up the minimum order quantity. Unfortunately as of today I’ve lost over 30 out of 85 orders and this is insufficient for me to make a group order of 100 units.

Secondly, the SirfVAtlas GPS integrated into the device has an issue which I am still trying to resolve. It has track smoothing enabled (whereby the gps reported position is not exact after a sudden change in direction – useful for making car gps software easier but not very good for gliderpilots) I didn’t notice this when flying with the device in Argentina as it was very windy – however in light wind conditions this can be a real problem as it will cause significant errors in the wind reported from normal circling algorithms. Under normal circumstances track smoothing can be disabled by the gps utilities software I already have installed in the unit – however the binary switches in this particular unit from YF do not respond. I am working with Vertica Sports who have the same sourced device to see if this can be addressed. So far my suppliers and OEM have been unable to help.

As it stands, the BriteNav will still be perfect for anyone who intends to configure it with external GPS, or FLARM.  However, given the insufficient level of interest and the intractability of the track smoothing problem I am not going to pursue the BriteNav further in its current form.

Moving Forward
I am working with Vertica to consolidate and re-evaluate interest in these devices – and I'm working with them to enable enable me to service lower order quantities, initially for external GPS driven applications only. The US price will be the same as the BriteNav.  I have a Vertica V1 on its way to me right now for evaluation.
Vertica have employed GPS engineers to work on resolving the track smoothing problem and I expect an update in the next 2 weeks.
If you still like the idea of the BriteNav/Vertica device and planned on using external GPS input, the device is still very attractive – and with this new arrangement I can get sunlight readable devices to you faster than I could with the previous order requirement, at the same price as the BriteNav.

Please let me know if you’re still interested in the Vertica form of the device.

Sorry this this been so painful – what started out as a service to the soaring community has turned into a messy situation and a huge time-sink all round.
I’ll update everyone again as soon as I get updates from Vertica.
Sincerely, Peter

POWER CONSUMPTION

OK - I got to measure power consumption in the glider.

While it was still charging the device measured 432mA - With a fully charged device this should drop to around 380-400mA. The Glidertools converter measured 15mA as advertized.

This compares reasonably favorably with the high 300mA's reported for similar earlier generation PNA's reported on the PostFrontal forum.

While I was at it I compared this to power consumption of other devices.

My Becker transponder drew 390mA under very low interrogation conditions

My radio sucked 30mA with no x or TX, and a whopping 1220mA  when transmitting.

BRITE-NAV TECHNICAL SPECS

Here are the technical specs of the device. I renamed it BRITE-NAV since iGlide was already used by some software company or other. I like BRITE-NAV better anyway!

While I was at the SSA Convention this weekend I compared the Brite-Nav with the Dell Streak Android device which is a viable device if you are ok with being restriced to XCSoar - I compared devices with Ramy Yanetz and the BriteNav is clearly brighter (about 20% brighter according to my carefully calibrated eyeball) in any full sun situation but I was interested in how nicely the Streak display and interface worked. The Streak is bigger and heavier - maybe too big for some cockpits. But not by much.

Brite-Nav runs all current WinCE6.0 compatible soaring software - SeeYou Mobile (my favourite), LK8000 and XCSoar, and is compatible with all the existing third party support hardware available on line from Naviter and GliderTools.

NEW BRIGHTER (950nits) UNIT!!




I have the new unit up and running - 50% brighter than the previous sample!!
950nits


I used this at the PreWorlds in Argentina, running on internal GPS with SeeYou Mobile. It was faultless and very accurate on final glides . I was flying a Std Cirrus and our tasks all completed with a 100m minimum altitude at 3km finish radius. It was dead nuts on every time. I mounted it inside the canopy on my rented Cirrus using the suction mount provided with the unit - worked great the whole contest and in 104F heat many days. 

I compared it directly with an Oudie - most dramatically, when looking into the sun and the Oudie and the Brite-Nav side by side, the Brite-Nav was completely visible. The Oudie screen was impossible to read. This is because of both the contrast ratio, the anti-glare coating and the brightness of the display.

I've put together 2 tutorial videos on YouTube
