We recommend to have a look on this. Very cheap components. Maybe be will do a workshop here in Berlin, based on this.

BOM:

Arduino pro mini 3.3 V Version!  1,57 €
    --  alternative 328P: 1,36 €
RFM 95 W 4,72 €
Ublox NEO-6M GPS Module GY-GPS6MV2 NEO6MV2 6.19 €
    --  alternative ?  2,16 € 
Ein / Ausschalter  0,08 € 
Battery LiPo 3.7 V 1200 mAh 5,30 €
    --  alternative: 4,61 €
3D enclosure (Thingiverse)


    total costs as of today, cheapest variant: 1,36 + 4,72 + 2,16 + 0,08 + 4,61 =  12,93 €
    and some cables and board
