Signal Strength
In order to calculate signature strengths, the first thing to determine is the Probe Sensor Strength.
Probe Sensor Strength
Probe Sensor Strength is determined by multiplying the probe's Base Sensor Strength with the Sensor Strength Multiplier.
| Probe Base Sensor Strengths | |
|---|---|
| Scan Probe | Base Sensor Strength |
| Combat Scanner Probe I | 20 |
| Core Scanner Probe I | 40 |
| RSS Core Scanner Probe | 45 |
| Sisters Combat Scanner Probe | 22 |
| Sisters Core Scanner Probe | 44 |
| Sensor Strength Multipliers | |||
|---|---|---|---|
| Type | Name | (Max)Bonus | Notes |
| Ship | Racial Scanning Frigate | 37.5% | 7.5% per skill level |
| Covert Ops | 50.0% | 10% per skill level | |
| Strategic Cruiser with Emergent Locus Analyzer | 50.0% | 10% per skill level | |
| Skills | Astrometrics | 25.0% | 5% per skill level |
| Astrometric Rangefinding | 25.0% | 5% per skill level | |
| Probe Launcher | T2 Launchers | 5.0% | |
| Sisters Launchers | 10.0% | ||
| Rigs | Gravity Capacitor Upgrade I | 10.0% | |
| Gravity Capacitor Upgrade II | 15.0% | ||
| 2 × Gravity Capacitor Upgrade I | 21.0% | ||
| Implants | 'Prospector' AR-802 | 2.0% | |
| 'Prospector' AR-806 | 6.0% | ||
| 'Prospector' AR-810 | 10.0% | ||
| Faction implants | Low-grade Virtue | up to 33.83% | varies per implant |
So, a maximum skilled capsuleer with 'Prospector' AR-810 implant and a full Low-grade Virtue set plugged in, flying in a Covert-ops frigate which has been improved with 2 Gravity Capacitor Upgrade I rigs, using RSS Core Scanner Probes launched from a Sisters Core Probe Launcher has the maximum Probe Sensor Strength of 198.39
Signal Strength
Each cosmic signature has a Signature Strength. The maximum Signal Strength picked up by your scan probes is determinded by the formula (downloadable excel sheet):
- Maximum Signal Strength = Base Signature Strength × Probe Sensor Strength × Probe Multiplier
| where: | ||
| Signature Strength | is site specific, | |
| Probe Sensor Strength | is described above, | |
| Probe Multiplier | is 0.257743125942 when using a single probe*). | |
| For each step above the probes minimum radius (= maximum strength), the maximum Signal Strength is divided by 2 | ||
The actual, Reported Signal Strength is commonly lower than the maximum: the distance to the target will influence the results. With multiple probes, the angles between the probes to the target signature also have a major effect on the signature strength reported in the scan results.
The scan probe deviation mainly affects the reported location and distance to the target signature. It does not seem to affect reported signature strength.
*) The value can be calculated by the empircal probe multiplier formula:
Where
X is the number of probes
b = 1.12344005211905E-09
c = 13.4252377061721
d = -7.73088260552265
offset = 0.766607925235115
