جهاز إرسال واستقبال بيانات فيديو منطاد الهواء الساخن على ارتفاعات عالية

TX900 يوصى به.
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?

شكرًا. 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 ساعات?

iVcan: Our battery is 7AH, normally we tested time is 2~4 hours, لا مشكلة. 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 (24~30 فولت), please try to source at your side.

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

بخصوص جهاز إرسال الفيديو, ما هي الترددات المتاحة? هل يمكننا أن نختار 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
أيضًا, 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. يتم تخصيص الهوائي وفقًا لهذا التردد.

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?

عميل:
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:
فيما يتعلق بكابل الترددات اللاسلكية, our engineer doesn’t recommend that you use so long. سيكون هناك انخفاض بمقدار 0.5 ديسيبل لكابل RF بطول متر واحد. For the 3-meter RF cable, the signal strength will be reduced by 1.5 ديسيبل.

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

في الحقيقة, the transmitter is very small, فمن الأفضل الحفاظ على مسافة قصيرة من جهاز الإرسال إلى هوائي جهاز الإرسال. يمكن أن يكون كابل إمداد الطاقة لجهاز الإرسال وكابل الإيثرنت من الكاميرا إلى جهاز الإرسال أطول حيث لا توجد خسائر مثل كابل التردد اللاسلكي.

عميل:
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, يرجى التحقق من الصورة أدناه.

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.

في الانطلاقة الأخيرة, استخدمنا أ 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. نحن غير راضين عن النتيجة التي تم تحقيقها ونبحث عن جهاز إرسال فيديو بالخصائص التالية: ​​1.2ghz frequency, كامل HD, قوة الترددات اللاسلكية أكبر من 500 ميجاوات, الوزن أقل من 100 جرام والاستهلاك لا يتجاوز 500 مللي أمبير.

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.
نقدم أيضًا نموذجًا مشابهًا لرصد الطقس والتنبؤ به في إسبانيا بواسطة بالونات الهيدروجين في الغلاف الجوي, والتي تحتاج إلى 150 كم.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, قوة الترددات اللاسلكية أكبر من 500 ميجاوات, الوزن أقل من 100 جرام والاستهلاك لا يتجاوز 500 مللي أمبير.
TX900-5W050km: 1.4Ghz frequency, كاميرا بدقة Full HD 1080P HDMI أو إيثرنت, قوة الترددات اللاسلكية 2 واتس, الوزن هو 142 جرام.

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