Global Positioning System / Advanced map
A more advanced version of the normal map, shows larger area as well as XYZ coordinates, also has zoom in/out features. Mobile just like the old map but will use power. Since it's a small screen, maybe something like 1 eu/s when in turned on. For realism it would have a "discovery mode" which takes more power but you need to use to discover more parts of the map, and then a "map mode" where it takes less power and just shows what you've already "discovered". Also since there are not exactly GPS sattelites floating around in minecraft orbit maybe add a launchable one. Maybe also add a constructable signal dish, but that would complicate things even further by needing code for signal strength and all that. (but if that is implemented, obviously the higher the signal dish the greater the area and if you go below too many blocks you lose signal). Not exactly sure how hard this would be too code, but I think it would fit in with tier 2 electronics (or tier 3, but I really dont see a GPS being as advanced as a lapotron crystal or quantum armor)
Recipe: GPS / Electronic Map
Note - Dynamite Remote = FreqTrans Empty cells = RE Batteries Diamond = Screen and Industrial diamond can be substituted with a normal diamond.
Recipe: Sattelite Dish
Ignore the rubber it's just there to try and keep the refined iron from moving to the side of the page.
Recipe: The Sattelite (I highly doubt this would be implemented)
: Note - Iridium Plate = Advanced Alloy / Carbon Plate Dynamite Remote = Sattelite Dish And if more advanced solar panels were to enter the game they would definitely be the ones that would fit on the sattelite.
