бийик тоолуу ысык аба шары видео өткөргүч маалымат трансивери

TX900 сунушталган.
We also have a buyer from European clients to use this model.
They do space weather monitoring, they need wireless video transmission equipment to monitor their equipment and download data.
The person also can upload the control command for some experiment types of equipment from the ground receiver to the balloon.
The bandwidth is 20mbps, is that ok for you?

Рахмат. TX900 is recommended.

Do you have a datasheet? Could you send me the antennas that work with this video transceiver? Do you have any compatible camera? How many cameras can we use with just one transceiver? Do you have a battery system or power system for the transceiver? Our flight will be 6 hours approx. Do you have batteries that will long 6 саат?

iVcan: Our battery is 7AH, normally we tested time is 2~4 hours, no problem. If you buy a 15AH battery, it should support 4~8 hours. Please check the attached picture.
The 10W PA transmitter and receiver need 3A@28V (24~30V), please try to source at your side.

Кардар:
This flight will be without tribulation. So we will power on all the equipment right before the flight.

Видео өткөргүч жөнүндө, кандай жыштыктар бар? Биз тандай алабызбы 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
дагы, do you provide RF cable from the video transmitter to the antennas?

iVcan:
1. There are three frequencies to choose from. If you choose 2.4G, then we will arrange the 2.4G Power Amplifier inside and the 2.4G transmitter and receiver antenna. So you should confirm which frequency you need before delivery. Антенна ушул жыштыкка ылайыкташтырылган.

2. We can offer you the RF cable from the transmitter to the antenna, how long do you need it for? It will be easy to have interfered if the cable is too long. So how long do you really need it for the best installation?

Кардар:
That would be perfect. I guess that sweeping the frequency to 2.4GHz will not affect the link budget and we still have 10W and 150Km coberture range?
Regarding RF cable we will need about 3m cable because we will put the video transmitter in the middle of the capsule and this has a 2.5m radius so 3m approx.

iVcan:
RF кабели жөнүндө, our engineer doesn’t recommend that you use so long. Бир метрлик RF кабели үчүн 0,5 дБ төмөндөйт. For the 3-meter RF cable, the signal strength will be reduced by 1.5 дБ.

In order to support long-distance at 150km, Can you use an RF cable that is less than 1 метр?

Чындыгында, the transmitter is very small, передатчиктен антеннага чейин кыска аралыкты сактоо жакшы. Камерадан өткөргүчкө чейин өткөргүч жана Ethernet кабели үчүн кубат берүүчү кабель узунураак болушу мүмкүн, анткени RF кабели сыяктуу жоготуулар жок..

Кардар:
I will check with the structure team that we need to put the video transmitter as close to the antenna as possible and get back to you with the RF cable length.

The system team asked me about the attachment system for the S transmitter that will be inside the capsule. Do you have any mounting brackets or recommendations? Ideally, the video transmitter will be placed inside a rack.

iVcan:
Regarding how to install it, сураныч, төмөнкү сүрөттү текшерүү.

There are four screws hole in the metal box, above the picture red arrow. It also can be bound by some cables like the one below.

In the last launch, we used a 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. We are not satisfied with the result achieved and we are looking for a video transmitter with the following characteristics: ​​1.2ghz frequency, FULL HD, RF power greater than 500mw, weight less than 100gr and consumption not exceeding 500ma.

iVcan:
May I know what is the distance from the ​stratosphere to the ground?
From the internet, I get that the distance is from 8km to 50km.
We also offer a similar model for Spain’s Weather Observation and Prediction by Hydrogen Balloons in the Atmosphere, which needs 150km.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, RF power greater than 500mw, weight less than 100gr and consumption not exceeding 500ma.
TX900-5W050km: 1.4Ghz frequency, Full HD 1080P HDMI or ethernet camera, RF күчү 2 Уоттс, weight is 142 гр.

I had a previous client with an application similar to yours. He used a hot air balloon to rise 50 үчүн 80 kilometers above the ground to monitor the environment. He just bought our long-distance wireless video transmitter and receiver to monitor whether the scientific instruments in the balloon are normal.
