[Spaceships, Ultra-Tech] On-board Sensors
In GURPS Spaceships 1 and 4, 0.5ton Enhanced Sensor Array (for SM+4 spacecrafts) costs $20K and it has 64x magnifications (Sensor Level 6) at TL11.
But in GURPS Ultra-Tech, Large Multi-mode Radar (p.UT65) costs $100K and weighs 100 lbs. And Hyperspectral Imaging Sensors Array (p.UT61) costs $160K, weighs 50 lbs and x128 magnifications at TL11. Why are the Spaceship Sensor Array so cheap and low-performanced? I guess Spaceship Sensor Arrays are more bulky than Ground-Vehicle Sensor Arrays so there may be no need for compactizations which increases its cost, but then why are the Spaceship Sensor low-performanced than Ground-Vehicle Sensor Arrays...? I think it makes no sense that 0.5tons of Spacecraft Sensor Arrays have low performance than much lighter Ground-Vehicle Sensor Arrays. Below is my Planet Surface Exploration Robot. Its sheet is made from GURPS Spaceship's rules. Well, is it senseless that making Ground Robots' sheet with GURPS Spaceship's rule? Quote:

I don't think the mass is at all unreasonable. The low cost might be, but unlike the UT systems these ones don't need rugged casings, and the whole system only needs one UI, saving on the cost of screens, input keyboards, and so on. Also, remember that the design system is intended to produce reasonable results across a huge range of sizes, and was originally for spaceships only. It's not surprising that at the very high and low ends of the scale and for non spaceships it gets a bit weird. I think it does a very good job, all things considered, but it's not perfect.

But when Spaceships' Sensor Array do the good performances on that long distance than Ultra-Tech's Sensor Array, I think Spaceships' Sensor Array should be expensive than Ultra-Tech's. Even SM+4 Science Sensor Array is cheaper than the set of Ultra-Tech sensors. Quote:

Re: [Spaceships, Ultra-Tech] On-board Sensors
In fact, the sum of the prices of PESA, LADAR, and RADAR described in Ultra-Tech (well, is there more sensors in Spaceships' setup?) is much expensive ($460K) than even SM+6 Spacecrafts' Enhanced Sensor Array (which costs $200K) but is much lighter (250 lbs) than SM+4 Spacecrafts' (which weighs 0.5ton).
I thought that the sensors intended for ground uses is difficult to build than that intended for space uses because ground has more obstacles for sensors to be operated than space, so that cost differences between these maybe make sense... But will it justify that the weight of ground sensors which are much lighter than space sensors? Last edited by Pectus Solentis; 09-20-2020 at 09:34 PM. |

But why the SM+4 Spaceships' Sensor is that much cheaper than the sum of Ultra-Tech devices is still a question to me. Ultra-Tech devices is 26 times expensive than SM+4 Spaceships' sensor... Last edited by Pectus Solentis; 09-20-2020 at 10:30 PM. |

Mis-submitted this post. Maybe I double-clicked Save button. Please ignore this post.

Re: [Spaceships, Ultra-Tech] On-board Sensors
Since Spaceships is the later document, the question should probably be reversed, why is UT so expensive compared to it? One thing we had seen IRL is a dramatic reduction in the cost of sensors, I can get an IR video camera the size of a largish cheese cube for $20 off Amazon (my fiancee used them to prove that we had mice last year). The same technology in UT costs 12x as much and weighs 4x as much.

Overall, I don't think doubling the mass is far off. Oh, and the UT gear is man-portable or light vehicle installations, so they're not including any cooling, maintenance spaces, etc. in their weight, whereas the Spaceships systems include all that stuff. EDIT: 'IRL' in this context means "In Real Life".
