Traveller scales and sensor rules

the sensor rules have changed a lot since then look at Megatraveller from 1989
and TNE from 1993

I still use High Guard myself and use a very bastardized set of sensor rules

I was just looking through some old Traveller rulebooks and reading up on
their scales and sensor rules. I thought I would share them for discussion:

1977 edition - Book 2/Starships

1" = 1000 miles 1 turn = ten minutes 1 G acceleration for one turn = 2" Earth
= 8" diameter planet Distance from Earth to Moon = 250" Minimum safe jump
distance = 100 planetary diameters Detection ranges: Civilian ships = 500"
Military vessels and scouts = 2000" Ships running silent cannot be detected at
> 100" Ships running silent and in orbit cannot be detected at > 10"

1983 edition - Charts and Tables

1 range band = 10,000 kilometers 1 turn = 1000 seconds 1 G acceleration for
one turn = 1 range band Minimum safe jump distance = 100 planetary diameters
Detection ranges:
Civilian ships = 15 range bands (one-half light second)
Military vessels and scouts = 60 range bands (2 light seconds) Ships running
silent cannot be detected at greater than half the usual range. Ships running
silent and in orbit cannot be detected at greater
than one-eighth the usual range.  Once detected, a vessel can be tracked
up to 90 range bands (3 light seconds)

I don't have copies of the first two (although I do have Traveller: 2300 as
well) could you elaborate?

IIRC, High Guard does not have sensor rules. Would you like to share your
bastardized version?

Thanks.

Jeff: Sure, once I gather all my notes again in one place.
