Bonjour Les Amis! My name is Nicolay, I am a paraglider pilot and an R&D engineer in the Ungravity project. And you are all one of the best competitors, adventurers, and mountaineers. Have you ever worried about whether your paragliding, or speedriding, or whatever else track will be recorded or get lost?

Just one day my own GPS get discharged during hike-n-fly and I lost a cool adventure, another time I landed in the water while performing acro and all my flight instruments had to be thrown out. I would like to understand how you - professional and leisure pilots today, solve this issue, going to the longest cross-country flights and doing SIV over the water :wink: ? And if you still have a headache whether to record a track or not, then I’m on the right way. And the world’s first solar-powered waterproof GPS vario - is really in demand.

I will be very happy if you say whether such a device (waterproof stand-alone GPS vario with a smartphone connectivity) is necessary for you or how do you solve the problems described. And if you liked my idea, then by this season we will have such an instrument!

Cher Ulisse31,

Many thanks for the comment. I promise to dispel your mistrust step by step, gradually revealing the information on this forum.

Here are two steps:

  • First of all, we will show a functional prototype this month to make it real for you and other people.
  • Second of all, we will create a fixed crowdfunding goal, following the steps of successful campaigns, and provide you with the money-back guarantee.

These are not functional prototypes I’m talking about, just some custom breadboards with which we were working a month ago. They combine all the components of the final circuit board, just with a simpler layout.

I hope that I managed to convince you of the seriousness of our intentions, dear flying friend. What else can I do to increase your confidence?

Best, Nicolay

allez on va faire les difficiles, mais 280€ pour un gps solaire qui enregistre que toutes les 10s pour 40 heures de track log, il y a mieux et moins cher sur le marché, alors oui il est étanche mais je me suis jamais mis à la baille et je ne compte pas commencer, va t il être compatible avec les iPhones et logiciel comme flyskyhy? beaucoup d’interrogation pour un objet de 280€, non? qu’en pensez vous?

Salut Nicolay,

un GPS de plus, pourquoi pas! C’est toujours bien de développer un nouveau produit.
Le côté waterproof me semble plus adapté au vol-biv (où on risque de se prendre la pluie, de se casser la gueule dans une rivière, etc) qu’à l’acro et au SIV (pas besoin de GPS). C’est un créneau qui n’a pas encore été exploité, me semble-t-il.

Bon développement à toi!

Cher Sacha,

I’m proud to tell you, that our challenge is to develop an instrument for the most extreme air adventures, which would go completely stand-alone, not requiring charging for GPS tracking, smartphone connectivity, and acoustic vario job. Please, note, that Ungravity does not have even a charge port, unlike other solar GPS.

To achieve this, we are using the world’s smallest GPS patch module, the industry’s lowest power consumption Bluetooth 4.1, smallest piezo sounder, and other improvements. That’s what drives our product cost - the best outlook and completely autonomous design.

I think, that you simply need a one to fly longest XC tasks, going vol-biv, or simply flying every day. Thank you for the question, I was glad to answer it!
Best, Nicolay

Merci beaucoup, Laurent.

I see some prospects for acro flying too. Using inertial and GPS tracking, it is possible to draw an acro maneuver within the tracklog. Perhaps, soon acro pilots will be showing their rides in Doarama the same way, XC pilots do with distance flying. What do you say about the real-time G-meter, which would indicate unloading and overloading just the same way, acoustic vario does with the vertical velocity?

By the way, the IP68 rating is reached with the water-resistant mesh vent, which can withstand immersion into the water to the depth of up to 1.5 meters, for up to 30 minutes. It is widely used in the smartphones industry. The left ones on the photo are especially for the vario, the right ones are Sony Experia Z3 water-resistant vents:

Thanks for wishes. Would be happy to hear from you about the acro-ideas.

Salut Nicolay,
Je continue à te répondre en français ici, mais tu peux continuer en anglais si tu préfères.

Je ne vois toujours pas l’utilité pour l’acro, un tracklog GPS ne donne rien sur un run (j’ai déjà regardé). Et la préoccupation d’un pilote acro n’est pas sa trajectoire, mais la beauté d’exécution des manoeuvres ( exemple: un héli et un triple twister ont la même trajectoire GPS, pourtant ça n’a rien à voir du point de vue de la difficulté technique et de l’agrément visuel). Idem pour le G-mètre: ça ne sert pas à grand-chose, ce qui compte c’est si l’aile reste ouverte ou non, si les connexions sont esthétiques, etc. Ca ne se mesure pas.
A mon avis tu fais fausse route avec ce public.

Pour le vol aventure, pourquoi pas. Attention, les petits buzzers sont difficiles à entendre s’ils ne sont pas très près de l’oreille.

Hi Laurent,
Thank you, I will reply in English.

I think that GPS tracking alone isn’t really able to show anything on the acro track. What I’m talking about is using inertial tracking with a 9-axis position sensor, which includes an accelerometer, a gyroscope, and a magnetometer. With the help of such a thing, you can visualize the motion in space with high accuracy. Adding a similar functionality to the usual GPS tracking, it is possible to see not only the trajectory but also the position in space, direction, and acceleration with a big resolution. I don’t exactly know, will it be helpful for acro pilots or not, but it seems that it is worth trying at least out of curiosity.

Regarding the real-time G-meter, the idea came from Ondrej Prochazka. He told me, that he would like to have such a feature, and this is a very simple thing to build. Some instruments already output acceleration on the screen, but I think that during the ride it is difficult to look at the display, so I come with the new idea of the sound G-meter by the analogy of vario.

In any case, thanks for your opinion about the audience. We would be very pleased to do anything useful for the acro, but Ungravity will not bet only on this.

https://4.downloader.disk.yandex.ru/preview/d28a17107a79b356952035c9b955931b4014a9e7a7536c04f5189fbaa1b0e5f1/inf/RldoFYa0Wm7yPLPsUn9mxgeafWX6nWN-Zh4dQ0eoWtZnrlWg9VhB8XqxFTUH0cHb-L8JMJe7UERZtkPZKtlJlg%3D%3D?uid=0&filename=Helmet_Facebook.png&disposition=inline&hash=&limit=0&content_type=image%2Fpng&tknv=v2&size=1280x626

And you are very right about the sound pressure. Ungravity has four different volume levels thanks to the amplifier circuit. But due to the fact, that solar power management can’t allow a lot of energy for really loud sound, we came up with the design on the helmet close to the ears. Now it is easy to hear the vario with any volume level.

Best, Nicolay

Intéressant. Sais-tu en quoi Ondrej pense que ça peut lui être utile?

Hi Laurent,
Sorry for the delay in answer.

Here it is:

https://4.downloader.disk.yandex.ru/preview/f277258ead25ab9ebf8836221cf2e4b2135eec2eacad6ebf3317de6960946dc0/inf/RldoFYa0Wm7yPLPsUn9mxv3Z1-X9DDbMC5jUyLOOr0QWCQJWgeMu1Tl01yP1CsIq9HhavlsSNE0teBVJHi7_fQ%3D%3D?uid=0&filename=2018-01-05_02-28-39.png&disposition=inline&hash=&limit=0&content_type=image%2Fpng&tknv=v2&size=1280x626

Speaking for myself, I do know at least two essential features for acro, which are easy to make with Ungravity: G-Log and a low altitude alarm. By the way, I’ve created a topic on justAcro forum to learn what acro functions pilots can imagine, but it looks so quiet there… https://justacro.com/forum/equipment/11166/waterproof-gadget-functions-acro

You and other forum members are very welcome to dream up, what futuristic features are desired in the possible device for acro!
Best, Nicolay

Bonjour tous le monde!
Our project does not stand still, and we receive a feedback from different people, including celebrities.

Ungravity was appreciated by such personalities as Bruce Goldsmith, Ondrej Prochazka, and Aaron Durogatti. At the moment we are working fast to prepare prototypes, which can be twisted in the hands and tested in the flight. Follow our promotion and subscribe to the Ungravity page on Facebook! https://www.facebook.com/ungravity.store/

c’est bien les nouveautés mais une la un marché tout petit petit et je ne vois vraiment pas l’utilité.a voir on sait jamais :wink:

#14

Alarme basse altitude c’est pas en effet!

#15

Cher Sacha,

Thanks for the comment! With Ungravity we mostly spend our passion, not money, but I do know that every flight starts with a wing and a vario.

I really like the direction in which the wings market develops. These lightweight technologies allow a dream to fly across the sky to weight like a package from a supermarket. Now imagine a small gadget, which satisfies your needs for flying and GPS tracking. And it requires no cables, no charging, no even care for working in the air and connecting to a smartphone.

I’m sure you will like it, and don’t care about the market thing!

#16

Hi Laurent,

I know 6 acro pilots in Norway who wants this. https://github.com/fhorinek/SkyDrop/issues/314 Can you tell your experience? The point is, as far as I understand, to fly safely to the landing zone after training over the water.

#17

Je pense que c’est surtout utile pour donner l’ordre au pilote de tirer le secours quand ça ne se passe pas bien.

Je n’ai jamais eu de problème avec ça, mais je connais un accident qui aurait pu être évité avec une alarme.

Concernant justacro, c’est assez mou le forum là-bas… essaie plutôt paraglidingforum si tu ne l’as pas encore fait.

#18

Thanks, Laurent. Let’s wish that others do not have these problems too.

I’ve created a discussion on Paraglidingforum at Flight Instruments topic: http://www.paraglidingforum.com/viewtopic.php?t=88472
Will create a discussion at Acro topic later.

Well, we just received the first batch of PCBs for Ungravity solar GPS vario ! Looking forward to assembling functional prototypes and trial alpha testing 8)

Bonjour les amis!

Over the past month, I have collected enough opinions about the project, and it turns out that the main stumbling block is the price. We have to work a little more to reduce the cost, but we must make it by the beginning of the season. Wish us luck!

P.S. Here the first step in reducing costs: a case made of hard nylon, manufactured using selective laser sintering technology instead of casting on automatic equipment. How do you like the snowy white color?
