Introduction

The following is an exerpt from Starfleet Academy courses, circa 2365, prior to the Borg invasion.

Settle down, cadets. We'll be covering the various standard scans and sensor operations that are possible on a starship today. As you will recall from our earlier session, passive sensors provide rough information that is easily inferred based on data receieved by the ship's computer, whether it's position, speed, bearing, etc. Active sensors, which have a range of 1/5th your passive sensors, use various means to determine additional information beyond what can be gathered from passive sensors. We'll be covering this in more detail as we go.

Scan

The most commonly used and basic sensor option is scan. This will provide a breakdown of all sensor contacts within range of your ship's passive sensors. A more advanced version, scan <contact> can be used to just get the basic details on one contact. Please note the examples on the holo.

Passive Scan

Scan provides perfectly adequate information for navigation, but there are times your Captain will want to know just a little more information about a contact. For that, there is pscan. The example is on the holo.

Passive Readings on CCV Azure ------------------------------------------------
   Class: United Federation of Planets Constitution-class Heavy Cruiser
Position: 39141.132 -23.347 988.183
 Heading: 1.557 -48.994                Bearing: 359.671 1.18
   Speed: None                           Range: 38949.6334903485
Location: Unclaimed Space
    Size: 288.6x127.1x72.2 m   [600000.0 tons]  <2648372.532 m^3>
------------------------------------------------------------------------------

This provides additional information about the class of the contact, it's location, detailed heading, detailed bearing, what territory it is currently residing in, and even it's size and mass. The latter is very critical in towing operations, as you wouldn't expect a shuttle to be able to tow a Constitution-class Heavy Cruiser like the one used in our example here.

Docked Scan

We'll now be moving into the realm of active sensors. The dockscan <contact> command will let you see what available landing or docking options there are on the contact. This uses passive sensors. Please note the holo for an example.

Dock Scan of CCV Azure -------------------------------------------------------
   Class: United Federation of Planets Constitution-class Heavy Cruiser
Position: 39141.132 -23.347 988.183
 Heading: 1.557 -48.994                Bearing: 359.671 1.18
   Speed: None                           Range: 38949.6334903485
------------------------------------------------------------------------------
Landing Areas:
 Shuttlebay: <nothing detected by passive sensors>
------------------------------------------------------------------------------
No detectable docking ports
------------------------------------------------------------------------------

In this case, there is only a singular Shuttlebay and no docking ports. Other ships might offer several shuttle bays and even a docking port or two, while stations offer a variety of docking ports and shuttle bays. Knowing what's available will keep a pilot from looking foolish by trying to dock to a ship that has no docking capability, or landing on a ship that has no shuttle bays.

There might be times when you're looking for a specific ship that might be landed or docked. For that, there is an active sensor option: dockscan/active <contact>. Please note the difference on the holo.

Dock Scan of CCV Azure -------------------------------------------------------
   Class: United Federation of Planets Constitution-class Heavy Cruiser
Position: 39141.132 -23.347 988.183
 Heading: 1.557 -48.994                Bearing: 359.671 1.18
   Speed: None                           Range: 38949.6334903485
------------------------------------------------------------------------------
Landing Areas:
 Shuttlebay: nothing
------------------------------------------------------------------------------
No detectable docking ports
------------------------------------------------------------------------------

In our example, there is nothing landed indicating that the shuttlebay is empty. Now, from the Azure's point of view, they'll have noticed the following:

[Captain's Chair: CCV Maroon has scanned docking facilities.]

Which, if your ship did not warn them, might cause an unfortunate response.

View Scan

The next option, while it uses active sensors, could be considered a passive scan as it does not notify the contact. Some ships just are worth taking a closer look at, while others might be running under a false transponder and that Terellian Freighter might actually be a Breen Cruiser. So, viewscan <contact> is shown on the holo.

                            `-------' 
------------------------------------------------------------------------------

Nice looking Constitution class ship, isn't she?

Tactical Scan

Now for the most commonly used active scan. You're coming up on a vessel which is showing signs of hostility and your Captain wants to know what kind of threat it is. For that, there is tacscan <contact>. Please note the holo for the results.

Tactical Scan of CCV Azure ---------------------------------------------------
Shield Status: UP  (400.0/400.0)          Life Signs: 1/1  (active/total)
       Target: Nothing
 Weapon Power: 0.0 (0.0%)
------------------------------------------------------------------------------
Num Name                 Recycle Yield   Range Arcs   Armed Mount Type
--- -------------------- ------- ------- ----- ------ ----- ------------------
 2x Phaser Banks          Never  20.0    20.0  FAPSVD     0 Omni-Directional  
 3x Torpedo Tubes         Never    ---    ---  FAPSVD     0 Omni-Directional  
------------------------------------------------------------------------------

In this case, the contact's shields are up at full power, their weapons are not powered, and they have 2 Phaser Banks and 3 Torpedo Tubes, all covering every firing arc. They are not currently targetting anyone. Their Phasers only have a range of 20 kliks, and have a yield rating of about 20. The shields have a rating of about 400, all typical for a first generation Constitution class. Detailed analysis will be covered in the Tactics courses for those interested in learning more.

The contact will have seen the following:

[Captain's Chair: Incoming tactical scan from CCV Maroon]

Alerting them to your scan.

Engineering Scans

There are a number of Engineering related scans available. The first, which has tactical implications as well as humanitarian uses, is damscan <contact>. If you'll note the holo, you'll see our Constitution-class ship has taken some damage.

Scan of CCV Azure ------------------------------------------------------------
   Class: United Federation of Planets Constitution-class Heavy Cruiser
Position: 39141.132 -23.347 988.183
 Heading: 1.557 -48.994                Bearing: 359.671 1.18
   Speed: None                           Range: 70.3259324067704
------------------------------------------------------------------------------
Warp Core             98.30% (     195.12)
Fusion Generators     85.86% (     127.30)
Hull                  99.91% (       4.27)
Armor                 33.31% (    3334.32)
Warp Drive            97.42% (      25.82)
Impulse Drive          0.00% (      10.00)
Sensors               99.90% (       1.81)
Shields                0.00% (     400.00)
Weapons               97.26% (      16.41)
Communications        72.63% (      27.37)
------------------------------------------------------------------------------

You'll notice that their impulse engines are destroyed as are their shields, with armor being the next most damaged item. That information can be useful for deploying workbees to do repairs, or even knowing whether it's safe to tow the vessel to the nearest starbase. In a combat situation, your Captain would most likely be a bit more judicious in their choice of attack to prevent destroying the target outright, though that will be covered in the Tactics courses for those so inclined.

The next scan option is to determine the fuel status of the target. If you receive a mayday from a ship out of fuel and find that it's a Breen Cruiser or Romulan Warbird, you might be dealing with a trojan horse. So your Captain would most likely request a fuelscan <contact> which'll return the results on the holo.

Scan of CCV Azure ------------------------------------------------------------
   Class: United Federation of Planets Constitution-class Heavy Cruiser
Position: 39141.132 -23.347 988.183
 Heading: 1.557 -48.994                Bearing: 359.671 1.18
   Speed: None                           Range: 38949.6334903485
------------------------------------------------------------------------------
Antimatter:             149.86844/150.0 (99.91)              
 Deuterium:             149.81582/150.0 (99.88)              
------------------------------------------------------------------------------

In this example, the contact is nearly full on fuel.

The last engineering scan is engscan <contact>. This outlines the power being generated by the contact. Seldom used, yet still useful in situations where your Captain might be dealing with a trojan horse. Please note the results on the holo.

Scan of CCV Azure ------------------------------------------------------------
   Class: United Federation of Planets Constitution-class Heavy Cruiser
Position: 39141.132 -23.347 988.183

------------------------------------------------------------------------------
System Name          Op %    Damage
-------------------- ------- -------------------------------------------------

This is also an alternative to the damage scan, in that it'll provide a breakdown on the damage experienced by the contact.

All three of these engineering scans notify the contact with the following:

[Captain's Chair: Incoming scans from CCV Maroon]

Cargo Scan

The final scan option is to scan a contact's cargo. Commonly used by Border Patrol, and ships dealing with smuggling operations, this provides you with a detailed breakdown of what a ship is hauling.

Cargo Scan of CCV Azure ------------------------------------------------------
Cargo Bay One
Commodity                      Amount    
------------------------------ ----------
Foods                          3750      
Cargo Bay Two
Commodity                      Amount    
------------------------------ ----------
Foods                          3750      
Cargo Bay Three
Commodity                      Amount    
------------------------------ ----------
Foods                          3750      
Cargo Bay Four
Commodity                      Amount    
------------------------------ ----------
Foods                          3750      
------------------------------------------------------------------------------

In our example, they're hauling Food in 4 different cargo bays. And, like most active scans, it provided the contact with the following:

[Captain's Chair: CCV Maroon has scanned the cargo sections.]

Conclusion

Thus ends our lecture on sensors and commonly used scans.
