・Laser coordinate specification mode
・Stable tracking of the same target
・Supports Mr. 猫好き's ELI2 output and ELI3 input.
・Easy to operate zoom


This product is an improved version of FCS Type 2.
It fixes two problems that were identified in FCS Type 2: the unstable behavior when a new target is found when the number of samples is 0, and the inability to track the same coordinates when the Autoaim button is pressed while in the laser coordinate specification mode.
Since the noise reduction algorithm uses the same least-squares linear function approximation as FCS Type 2, FCS Type 3BFCS Type 3B outputs more stable values than FCS Type 2, but has a larger error when tracking a target with curvilinear motion.
In addition, this product is compatible with ELI2 output and ELI3 input of Mr. 猫好き, so it can be combined with his products.

ELI2 output
Number
1: X coordinate
2: Y coordinate
3: Z coordinate
4: X velocity
5: Y velocity
6: Z velocity
ON/OFF
1: Target detection

ELI3 input
Number
1: X coordinate
2: Y-coordinate
3: Z-coordinate
ON/OFF
1: Face the specified direction
When using the ELI3 terminal, set the coordinates at which you want the FCS to point. After setting the coordinates, send a pulse signal to the on/off channel.

FCS Type 2: buggy, linear function approximation
FCS Type 3A: bug fixed, linear approximation
FCS Type 3B: bug fixed, quadratic function approximation

1. Turn the power on by turning the key.
2. Aim at the target you wish to lock on to.
3. When the target is locked on, it is marked with a red circle.
4. Turn on the Autoaim button to automatically track the target.
5. If you want to use the laser coordinate mode, turn on the Laser Mode button.
