![]() In my experience you can expect those numbers to double, if not more. However, I'd take those numbers with a grain of salt, as they assume completely nominal trajectories, which you will rarely have. It does much more than that, such as tell you the weight of your spacecraft and how much delta-V you have, but if you don't want the autopilot and just the vessel information, Kerbal Engineer is just the ticket.Īs for the amount of delta-V you need to get to other planets, the KSP wiki has a handy reference list on the page for Kerbin. Some people consider it cheating, but they're the types that enjoy flying everything. If you don't mind using mods, MechJeb is a great autopilot that will fly your launches and spacecraft for you. Personally I've never watched his tutorial vids, but his Interstellar Quest and some others are great. Certainly simplifies spaceflight.Ī good many people enjoy Scott Manley's videos on YouTube. In all seriousness, the navball is your friend here, and really all you have to do is match the inclination of your target and then burn until you're caught by the gravity of wherever you want to go-as KSP does not use n-body physics, but rather patched conics. The LV-N is usually what people use for interplanetary missions, as it has a high Isp and acceptable TWR. However, its TWR (thrust to weight ratio) is pathetic and you'll be tearing your hair out at hour-long burns. That same probe has a high Isp, and therefore a huge change in velocity. An ion probe and a huge transport may have the same delta-V, but an inordinately different amount of fuel. On the other hand the Comms DTS-M1 is heavier although the masses are so low that they are probably not important.Fuel: the amount of fuel is irrelevant-the delta-V is all that matters. In a very specific case when only batteries are used the Comms DTS-M1 is better than the Communotron 16, because both use the same amount of electric charge per Mit. The fast Communotron 88-88 uses almost twice the electricity for the same amount of data, so should possibly be avoided on craft that have a less than generous electricity supply. There is no "best" or "better" here, for most purposes. The impatient may prefer to use the faster antenna (but should ensure that they can generate electricity fast enough, or have a sufficiently large battery supply to keep it running), but even the slowest antenna transmits the largest science experiment data in a tolerable time. Prior to Version 1.2, antenna choice was commonly a matter of aesthetics, choosing based on what fits on the craft in question, and looks good. A list of Antennas and their range can be found in CommNet. Stronger antenna are required to transmit science and control probes the further you are away from the KSC. The only exception is the MPO probe which has an embedded 2G relay antenna with the same specifications than the RA-2 antenna.Ī size comparison of the antennas available as of v1.2įor most purposes, it depends how far away you are to Kerbin. Although they have packet specifications in their cfg file they are unable to transmit science. ![]() ![]() When the Transmit button is used and multiple antennae are available, the game chooses the best one based on the cost and time per Mit.Įvery probe or command module has an embedded 5k direct antenna. Aborting any transmission of scientific data will destroy any remaining data that was to be sent. If the antenna's own right-click menu command is used to initiate the transmission, it will attempt to immediately transmit all data stored in all science modules on the craft. When the transmit button is pressed while reviewing experiment results, an antenna will automatically deploy to perform a transmission and then retract after completion. The transmission would be 13 packets and consume 78 ⚡ in 7.8 seconds. For example, consider a materials study (25 Mits) transmitted through a Communotron 16 Antenna (2 Mits/packet, 0.6 s/packet, 6 ⚡/packet). A transmission's total time and required energy can be determined from these properties. Transmissions group the data in a whole number of packets, so the last packet may not be fully utilized. The packet sizes are 1 Mit for the RA-2 Relay Antenna, 3 Mits for the HG-55 Direct Antenna, and 2 Mits for all other stock antennae. ![]() The direction and distance as well as the visibility of the facility, that there are no planets or moons in between, don't affect the transmission in any way.Įach antenna has three transmission properties: packet size (Mits/packet), duration (s/packet), and required energy (⚡/packet). The transmission is suspended if there is insufficient electric charge available, and automatically resumes once sufficient stored power is accumulated. When an antenna transmits data to the Research and Development facility, it consumes an amount of electric charge for each packet of data. ![]()
