IsoLOG 3D Block
IsoLOG 3D block: Main settings for the IsoLOG 3D DF tracking antenna.
The IsoLOG 3D DF is an ultra wide band antenna. It consists of up to 16 sectors with up to 64 antennas and offers a switch/rotation rate down to 1µs per antenna/sector. The result is a perfect real-time all frequency 3D RF tracking within a wide frequency range. The IsoLOG 3D DF antenna is a "must have" for our drone detection (DD) and directional finding (DF) software.
The IsoLOG 3D block offers full control over the IsoLOG 3D DF antenna incl. IP setup, element/sector mask configuration, mode setup (chopper vs remote switching), switching time setup, GPS setup (internal or manual). In Addition the GPS block offers a powerful MAP (2D, 3D, Topo and Topo with buildings).
Left hand side inputs:
- GPS (Optional GPS data, if internal GPS not used)
Right hand side outputs:
- RF (RF | Meta data)

Hi Team,
I want to export the antenna status data to external integrated systems. I'd like to know how to export segment or sector data through RTSA software, which segment or sector of 3D antenna is connected with the RF signal at this exact moment？
The IsoLOG block doesn't output that information. It is intended for controlling the antenna, not for data analysis. At most you could attempt to check the currently configured element and sector using the script block, but depending on your timing requirements that may not be accurate enough.
Alternatively you can get that information from the V6 block if the antenna RF output is connected to a Spectran V6 receiver. When connected to a HTTP server the stream will contain an "antenna" element for each sample with "azimuth" and "declination" attributes that can be used to deduct element and sector numbers (if necessary).
If you only have the antenna itself, you'll have to use its builtin HTTP interface to read its current configuration (which is what the IsoLOG RTSA block does). However you will have to account for latency yourself in that scenario, which again depending on your timing requirements might be an issue.

What is the exactly meaning for data, "azimuth":2.3561944962,"declination":-0.78539818525", from the HTTP server stream? Is the unit " 0°－360°"? and how to understand the minus character, "-" ？
Could you please help me for the confusion？ What is the exactly meaning for data, "azimuth":2.3561944962,"declination":-0.78539818525", from the HTTP server stream? Is the unit " 0°－360°"? and how to understand the minus character, "-" ？
Values are defined in radian, you need to multiply them with 180 / PI to get degree. Note that this already includes any offsets specified in the IsoLOG configuration.
There seems to be something wrong with the declination values though, they might be inverted. Just treat -45° as 45°.
Thank you for your reply.
