Why are player corporation standings to NPC entity (factions, corporations and agents) important?
Player corporation standings control access to Jump Clones and allow corporations to anchor POS in high security systems. They also affect the amount of tax you pay in stations for certain activities. If your corporation has a standing of +8.00 or greater to an NPC corporation, the NPC corporation has medical clone facilities and you have the Infomorph Psychology skill trained, you are able to install Jump Clones at the NPC corporation stations. To anchor a POS in high-sec (0.4 to 0.7) systems, your corporation needs to have standings with the relevant faction of 10x the security status of the system. For example, to anchor a POS in +0.6 Caldari space, your corporation requires a Caldari faction standing of at least +6.0. For these purposes the real security status of the system is not considered.
