transceiver data pemancar video balon udara ketinggian tinggi

TX900 direkomendasikan.
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?

Terima kasih. 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 jam?

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.

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

Mengenai pemancar video, berapa frekuensi yang tersedia?? Bisakah kita memilih? 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
Juga, 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. Antena disesuaikan dengan frekuensi ini.

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?

Klien:
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:
Mengenai kabel RF, our engineer doesn’t recommend that you use so long. Akan ada pengurangan 0,5dB untuk kabel RF satu meter. 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 meter?

Faktanya, the transmitter is very small, lebih baik menjaga jarak pendek dari pemancar ke antena pemancar. Kabel power supply untuk transmitter dan kabel ethernet dari kamera ke transmitter bisa lebih panjang karena tidak ada loss seperti kabel RF.

Klien:
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, silakan cek gambar di bawah.

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.

Dalam peluncuran terakhir, kami menggunakan a 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. Kami tidak puas dengan hasil yang dicapai dan kami sedang mencari pemancar video dengan karakteristik sebagai berikut: ​​1.2ghz frequency, HD PENUH, Daya RF lebih besar dari 500mw, berat kurang dari 100gr dan konsumsi tidak melebihi 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.
Kami juga menawarkan model serupa untuk Pengamatan dan Prediksi Cuaca Spanyol dengan Balon Hidrogen di Atmosfer, yang membutuhkan 150km.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, Daya RF lebih besar dari 500mw, berat kurang dari 100gr dan konsumsi tidak melebihi 500mA.
TX900-5W050km: 1.4Ghz frequency, Full HD 1080P HDMI atau kamera ethernet, daya RF 2 watt, berat adalah 142 gram.

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