CV 90 MK.IV data and discussion

Because Ozelot doesn’t use commander sight for it, while Janus is commander sight?

The ozelot doesn’t have a commanders sight, but it has an “search radar antenna” .

But going purely by description the functionality is the same right?

I mean… Ozelot uses dedicated sensor for this, while Janus is commander sight in first option and only after that it’s “IRST”.

TBH, CV90 is not unique with this, cuz 2S38 and iirc Frecia also can use their commander sights like IRST.

Slight miscommunication there, the janus system is described as an “fcs director” and “Fire Control Director for Weapons” on the first brochure.
I.e. It finds and locks targets before passing the information to the fire control, which is optionally part of the janus package or comes with the vehicle (which is the case with the cv90), there’s a diagram on the first pamphlet.

So is the confusion here in the vehicle having an irst system and digital fire control system that work together, with the disagreement being whether the fire control system actually acts on the information passed through by the irst?
Because I’ve been assuming the standalone irst functionality inherent in the device should at least function as the irst systems on other vehicles such as the ozelot, while the desired functionality is just the irst information being given to the tank’s fire control as explicitly stated in the documents.

The janus system is the commander sight on the freccia.

Because that has a separate added FCS module (hence the name “+FCS”) that we would need to prove existed in the CV90 Mk.IV. The first brochure is also the naval and defence version: “This system is among the best naval solution for E/O surveillance and short-to-medium range defence”.

The second brochure that is the specific version for land vehicles: “JANUS Digital-Land is a modular dual axis gyro-stabilized sight for MBTs and AFVs” , doesn’t have that description.

Should be PBV-V CV9030CZ produced in Czech Republic, some differences between this and the pre-production model from Sweden.

The janus system already has fire direction capability in game on all vehicles it is modeled on, it’s activated using the commander fire control system.
The fcs module used in the freccia/cv90 is the one the vehicles already came with, the ir/tv track simply being handed over to the fire control system.
What I’m requesting is the ability of it to track targets, as already depicted in game on the freccia, to be shared with the cv90mkiv, and hopefully it to gain irst functionality as described in all manufacturer documentation.

We’ve already established that the cv90’s fire control system does all the range and lead computation on targets being tracked, and that it is equipped with a sight that does automatic tracking, so shouldn’t the target tracking and lead computation happen at the same time?

The cv90 mk3 and mk4 have a fully digital system, meaning add on features like the janus simply plug directly into their fire control system, hence the diagram in the brochure.

So we know the vehicle can shoot based on the view from the janus system (already depicted in game, and inherent to the digital fire control) and that the janus system can on its own track targets. All that’s left is to say the janus system can track targets while being used as the fire control for the cv90.

Being easy doesn’t mean it has happened.

Then prove that?

Just to be clear, its literally impossible for the janus system to do ANYTHING if its not plugged into the fire control system. It is a ball of cameras, the entirety of the I/o is in the vehicle, if the janus system is not connected to the fire control system then it is not connected to the screen the commander and gunner use. If you’re claiming it’s not connected to the vehicle then you’re claiming the system is entirely non functional and that the depictions both in game and by bae are lies.
As the diagram in the brochure depicts, the janus sensor ball is an irst, it then connects to the fire control system, all manufacturers involved have made it clear that it is a plug and play system that literally connects via an Ethernet wire.
I used the word “say” as a less accusatory alternative to admit, ie the thing to be implemented.

I don’t know what you’re trying to say here or how that proves anything that i pointed to in my reply.

You replied

“Being easy doesn’t mean it has happened.”

In response to the assertion that the janus system can plug directly into the fire control unit. The issue here is that in order for the JANUS system to have any functionality whatsoever it has to be plugged into the same processor that is the fcs. You cannot have a video get from a camera to the screen in front of the commander unless the two are connected.
As shown in the diagram

the janus system is connected to the computer/fcs before the computer/fcs can output that video to the operator. So either the system is purely decorative and lacks any function, or its connected to the fire control computer. This is what I was trying to say when talking about the unified digital system of the cv90, if the janus system is connected to it, then the janus system is connected to it. There is no half option where only the raw video feed is available to only the commander.

That description and diagram is from the naval version (the one called “+FCS”). We would need to prove that that functionality exists in the system installed in the CV90 since it’s an optional addon that isn’t described in the brochure for the land vehicle version.

As i said before:

The system being capable doesn’t mean that that functionality has been installed/integrated into the CV90.

Let me simplify this again: The Janus system outputs information, the commander views this information on his console, the commander’s console is connected to the vehicle’s computer, therefore, if information is to get from the janus system to the commander’s console it must move through the vehicle’s computer.

I’m surprised you haven’t ran into the “NATO Generic Vehicle Architecture” before.

Updated version of that diagram AEP-4754 Volume II fig 2
NVGA power architecture

This is the system that the janus system outputs to “Completely digital system, designed in compliance with the most modern NATO-VGA architecture that puts it at the forefront in the production of suites dedicated to the multiple vehicle platforms existing on the market. The use of standard digital interfaces simplifies integration and configuration within an Observation System.”

So let me simplify as well, information being displayed on a screen doesn’t mean that the FCS can direct the gun to point to that information automatically.

The UTAAS sight is also capable of video tracking but it needs an extra module to be capable of doing so. The JANUS system is capable, but need “FCS” module (as described in the naval brochure) to be able to direct the gun. If the vehicle doesn’t have that function in it’s FCS it can’t lay the gun to the video track.

I understand you’re frustrated with me but please hold on for a moment. I think I confused you by using the naval brochure rather than diving into the nato vga system.

The gun of the cv90 is directed by the fire control system (FCS is the acronym for ‘fire control system’), it’s what accounts for leading targets and the like. On later cv90 models such as the mk3 and mk4 the fire control is done as part of a larger computer system that everything else connects to.
So the consoles that the crew members use function by connecting to the fcs and getting their data from that. This means that if a system like the JANUS is connected to the vehicle it is first connected to the fcs, then the fcs connects further on to things like the crew consoles where information can be displayed. Even something as simple as finding the range to the target is done by the crew using a console to order the fcs to find the range, then the fcs ordering the rangefinder equipped module (utaas or janus) to lase the target, then the module passing the range back to the fcs, then the fcs finally displaying the range to the crew and adjusting the gun accordingly.
