taas nga altitude hot air balloon video transmitter data transceiver

km-30km-taas nga distansya-wireless-video-transmitter-receiver-transmission-transceiver girekomendar.
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?

Salamat. TX900 is recommended.

kliyente:
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 mga oras?

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 (24opsyonal nga grado sa distansya), please try to source at your side.

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

Mahitungod sa video transmitter, unsa ang mga frequency nga anaa? Makapili ba ta 2.4 GHz as an option or it has to be 1.4GHz or 800MHz?
usab, 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. Ang antenna gipahiangay sumala sa kini nga frequency.

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?

kliyente:
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:
Mahitungod sa RF cable, our engineer doesn’t recommend that you use so long. Adunay usa ka pagkunhod sa 0.5dB alang sa usa ka metro nga RF cable. 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 metros?

Sa pagkatinuod, the transmitter is very small, mas maayo nga magpabilin sa usa ka mubo nga gilay-on gikan sa transmitter ngadto sa transmitter antenna. Ang power supply cable alang sa transmitter ug ethernet cable gikan sa camera ngadto sa transmitter mahimong mas taas kay walay mga pagkawala sama sa RF cable.

kliyente:
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, palihug check sa ubos nga hulagway.

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.

Sa kataposang paglusad, among gigamit a 1.2 GHz video transmitter to transmit images from ​​the stratosphere to the ground. Wala kami matagbaw sa nakab-ot nga resulta ug nangita kami usa ka transmiter sa video nga adunay mga musunud nga kinaiya: ​​1.2ghz frequency, FULL HD, RF gahum labaw pa kay sa 500mw, gibug-aton nga ubos sa 100g ug konsumo nga dili molapas sa 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.
Nagtanyag usab kami og susama nga modelo alang sa Pag-obserbar sa Panahon sa Espanya ug Pagtagna pinaagi sa Hydrogen Balloons sa Atmosphere, nga nagkinahanglan ug 150km.
The above model TX900-5W-50km is recommended.
​Your need: 1.2ghz frequency FULL HD, RF gahum labaw pa kay sa 500mw, gibug-aton nga ubos sa 100g ug konsumo nga dili molapas sa 500ma.
TX900-5W050km: 1.4Ghz frequency, Full HD 1080P HDMI o ethernet camera, Gahum sa RF 2 watts, timbang kay 142 gramos.

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