Балони баланди ҳавои гарм интиқолдиҳандаи видеои интиқолдиҳандаи маълумот

TX900 тавсия дода мешавад,.
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?

ташаккур. 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 соат?

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 (24дараҷаи ихтиёрии масофа), please try to source at your side.

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

Дар бораи интиқолдиҳандаи видео, басомадҳои дастрас кадомҳоянд? Оё мо интихоб карда метавонем 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
ҳамчунин, 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 мувофиқи ин басомад танзим карда мешавад.

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?

мизоҷ:
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:
Дар бораи кабели RF, our engineer doesn’t recommend that you use so long. Барои як метр кабели РБ 0,5 дБ кам мешавад. For the 3-meter RF cable, the signal strength will be reduced by 1.5 DB.

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

Дар асл, the transmitter is very small, аз передатчик то антеннаи передатчик масофаи кутох нигох доштан бехтар аст. Сими таъминоти барқ ​​барои интиқолдиҳанда ва сими Ethernet аз камера ба интиқолдиҳанда метавонад дарозтар бошад, зеро ҳеҷ гуна талафот ба монанди сими RF вуҷуд надорад.

мизоҷ:
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, лутфан тасвири зеринро санҷед.

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.

Дар барориши охирин, мо истифода бурдем 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. Мо аз натиҷаи бадастомада қаноатманд нестем ва мо интиқолдиҳандаи видеоро бо хусусиятҳои зерин меҷӯем: ​​1.2ghz frequency, FULL HD, Қувваи RF зиёда аз 500 мВт, вазни камтар аз 100 грамм ва истеъмоли на бештар аз 500 м.

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.
Мо инчунин як модели шабеҳро барои мушоҳида ва пешгӯии обу ҳавои Испания тавассути пуфакҳои гидрогенӣ дар атмосфера пешниҳод мекунем, ки 150 километр лозим аст.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, Қувваи RF зиёда аз 500 мВт, вазни камтар аз 100 грамм ва истеъмоли на бештар аз 500 м.
TX900-5W050km: 1.4Ghz frequency, Full HD 1080P HDMI ё камераи ethernet, Қувваи RF 2 ватт, вазн аст 142 грамм.

I had a previous client with an application similar to yours. He used a hot air balloon to rise 50 ба 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.
