उच्च उंचीवरील हॉट एअर बलून व्हिडिओ ट्रान्समीटर डेटा ट्रान्सीव्हर

TX900 शिफारस केली आहे.
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?

धन्यवाद. TX900 is recommended.

क्लायंट:
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 तास?

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 (24पर्यायी अंतर ग्रेड), please try to source at your side.

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

व्हिडिओ ट्रान्समीटर बद्दल, उपलब्ध फ्रिक्वेन्सी काय आहेत? आम्ही निवडू शकतो 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
तसेच, 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. या वारंवारतेनुसार अँटेना सानुकूलित केला जातो.

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?

क्लायंट:
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:
आरएफ केबल बद्दल, our engineer doesn’t recommend that you use so long. एक मीटर आरएफ केबलसाठी 0.5dB कमी केले जाईल. For the 3-meter RF cable, the signal strength will be reduced by 1.5 डीबी.

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

खरं तर, the transmitter is very small, ट्रान्समीटरपासून ट्रान्समीटर अँटेनापर्यंत थोडे अंतर ठेवणे चांगले. कॅमेऱ्यापासून ट्रान्समीटरपर्यंत ट्रान्समीटर आणि इथरनेट केबलसाठी वीज पुरवठा केबल लांब असू शकते कारण आरएफ केबलसारखे कोणतेही नुकसान नाही..

क्लायंट:
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, कृपया खालील चित्र तपासा.

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.

क्लायंट:
शेवटच्या प्रक्षेपणात, आम्ही a वापरले 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. मिळालेल्या निकालावर आम्ही समाधानी नाही आणि आम्ही खालील वैशिष्ट्यांसह व्हिडिओ ट्रान्समीटर शोधत आहोत: ​​1.2ghz frequency, फुल एचडी, 500mw पेक्षा जास्त RF पॉवर, वजन 100gr पेक्षा कमी आणि वापर 500ma पेक्षा जास्त नाही.

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.
आम्ही स्पेनच्या हवामान निरीक्षणासाठी आणि वातावरणातील हायड्रोजन फुग्यांद्वारे अंदाज लावण्यासाठी समान मॉडेल ऑफर करतो, ज्यासाठी 150 किमी आवश्यक आहे.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, 500mw पेक्षा जास्त RF पॉवर, वजन 100gr पेक्षा कमी आणि वापर 500ma पेक्षा जास्त नाही.
TX900-5W050km: 1.4Ghz frequency, पूर्ण HD 1080P HDMI किंवा इथरनेट कॅमेरा, आरएफ शक्ती 2 वॅट्स, वजन आहे 142 ग्रॅम.

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