高高度熱気球ビデオ送信機データトランシーバー

TX900 がおすすめ.
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?

感謝. TX900 is recommended.

クライアント:
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 営業時間?

iVcan: Our battery is 7AH, normally we tested time is 2~4 hours, 問題ない. 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オプションの距離グレード), please try to source at your side.

クライアント:
This flight will be without tribulation. So we will power on all the equipment right before the flight.

ビデオ送信機について, 利用可能な周波数は何ですか? 選べますか 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
さらに, 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. アンテナはこの周波数に応じてカスタマイズされます.

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?

クライアント:
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ケーブルについて, our engineer doesn’t recommend that you use so long. 1メートルのRFケーブルで0.5dB減少します. For the 3-meter RF cable, the signal strength will be reduced by 1.5 デシベル.

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

実際には, the transmitter is very small, 送信機から送信機アンテナまでの距離を短くすることをお勧めします. 送信機用の電源ケーブルとカメラから送信機までのイーサネットケーブルは、RFケーブルのような損失がないため、長くすることができます.

クライアント:
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, 下の画像をご確認ください。.

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.

クライアント:
前回の打ち上げでは, 私たちはを使用しました 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. 達成された結果に満足できず、次の特性を持つビデオ送信機を探しています。: ​​1.2ghz frequency, フルHD, 500mwを超えるRF出力, 重量は100gr未満、消費量は500maを超えない.

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.
また、大気中の水素気球によるスペインの気象観測と予測にも同様のモデルを提供しています。, 150km必要です.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, 500mwを超えるRF出力, 重量は100gr未満、消費量は500maを超えない.
TX900-5W050km: 1.4Ghz frequency, フル HD 1080P HDMI またはイーサネット カメラ, RFパワー 2 ワット, 体重は 142 グラム.

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