고고도 열기구 비디오 송신기 데이터 트랜시버

TX900 추천.
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?

감사. TX900 is recommended.

고객:
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 시간?

iVcan: Our battery is 7AH, normally we tested time is 2~4 hours, 괜찮아요. 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 (24선택적 거리 등급), please try to source at your side.

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

비디오 송신기에 관하여, 사용 가능한 주파수는 무엇입니까? 우리가 선택할 수 있을까요? 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
또한, 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. 안테나는 이 주파수에 따라 주문을 받아서 만들어집니다.

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?

고객:
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 케이블에 대하여, our engineer doesn’t recommend that you use so long. 1미터 RF 케이블의 경우 0.5dB 감소. 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 미터?

사실로, the transmitter is very small, 송신기에서 송신기 안테나까지 짧은 거리를 유지하는 것이 좋습니다. 송신기용 전원 케이블 및 카메라에서 송신기까지의 이더넷 케이블은 RF 케이블과 같이 손실이 없으므로 더 길어질 수 있습니다..

고객:
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, 아래 그림을 확인하시기 바랍니다.

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.

고객:
지난 출시 당시, 우리는 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. 우리는 달성된 결과에 만족하지 않으며 다음과 같은 특성을 가진 비디오 송신기를 찾고 있습니다.: ​​1.2ghz frequency, 풀 HD, 500mw보다 큰 RF 전력, 무게는 100gr 미만이고 소비량은 500ma를 초과하지 않습니다..

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.
우리는 또한 대기 중 수소 풍선을 이용한 스페인의 기상 관측 및 예측을 위한 유사한 모델을 제공합니다., 150km가 필요해요.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, 500mw보다 큰 RF 전력, 무게는 100gr 미만이고 소비량은 500ma를 초과하지 않습니다..
TX900-5W050km: 1.4Ghz frequency, 풀 HD 1080P HDMI 또는 이더넷 카메라, RF 전력 2 w, 무게는 142 그램.

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