T5 space range bands and GURPS

hal · 09-12-2018, 09:31 AM

Hello Folks,
I'm trying to translate some of the T5 game mechanics into terms that are comparable to what GURPS would recognize. I want to be certain that I understand the range band from T5 and hope that someone can confirm the data that I'm looking at:

To wit:

S=17, 7 light days
S=16, 42 light hours
S=15, 10 light hours
S=14, 5 light hours
S=13, 83 light minutes or 1,500 million Km
S=12, 30 light minutes or 500 million Km
S=11, 8 light minutes or 150 million Km
S=10, 100 light seconds or 50 million Km
S=09, 5 million km
S=08, 2,500,000 km
S=07, 500,000 km
S=06, 250,000 km
S=05, 50,000 km
S=04, 5,000 km
S=03, 500 km
S=02, 50 km
S=01, 5 km

The reason I'm asking is because the example given in Traveller 5th edition for an astrogation check to have a ship end up in space band 12 from say, a star. Putting this into perspective, 100 earth diameters is 1,274,200 km. An AU is 149,597,871 km.

So, if a character wants to plot an exit from Jump space to about Earth's orbit, he'd be plotting to a space band 11. When a jump is potentially not entirely accurate, it could end up between 11-5 (or space band 6) or 11+5 (space band 16) in distance from the Sun. 42 light hours is 42 hours x 3600 seconds per hour x 299,792 km per second (speed of light) results in a final distance that is 45,328,550,400 km away (or 28,165,855,404.44 miles).

Does this seem right? I'm using the "Scatter" rules from T5 as far as accurate jumps or inaccurate jumps.
