The slide closure of claim 1, the slide closure including at least one spring biasing the first and second closing surfaces toward one another so that the nip gap is minimized. 10. The slide closure of claim 1, wherein the slide closure body is also configured to move in the opposite direction along the overlapping substrate edges and separate the edges such that the complementary touch fasteners disengage. 11. The slide closure of claim 10, further including structure that connects the first and second closing surfaces including a spanning member, the structure and closing surfaces defining the two channels each open to receive one of the substrates from one side of the slide closure, the channels having a width such that at least some of the widths of the first and second touch fasteners overlap between the closing surfaces and diverge around the spanning member, the spanning member having a first separating surface, a second separating surface, and a nose in between the two separating surfaces, the nose pointing toward the nip and the spanning member adapted to cleave and separate the engaged touch fasteners when the slide closure body is moved in the opposite direction along the overlapping substrate edges. 12. The slide closure of claim 1, wherein the slide closure body is configured to move in the opposite direction along the overlapping substrate edges and bring the edges together such that the complementary touch fasteners engage. 13. The slide closure of claim 12, wherein the first and second closing surfaces define a first pair of closing surfaces converging to a first nip, the slide closure body further including a second pair of closing surfaces that converge toward one another to a second nip defining a gap with a dimension sufficiently small to bring the first and second touch fasteners into engagement. 14. A slide closure for joining first and second strips having complementary touch fasteners thereon, comprising: first and second closing arms that are spaced apart at their closest point across a nip defining a gap with a dimension sufficiently narrow to bring the first and second touch fastener strips into engagement; and a spanning member between the first and second closing arms and connected thereto at opposite sides, the spanning member and closing arms together defining two channels opening from opposite sides of the slide closure and separated by the spanning member, the channels each being configured to receive one of the touch fastener strips such that the first and second touch fastener strips overlap within the slide closure, the slide closure thus being configured to move in a first direction along the touch fastener strips to bring the complementary touch fasteners into engagement, and in a second, opposite direction to separate the touch fasteners, wherein the first and second closing arms are biased toward one another so that the nip gap is minimized. 15. The slide closure of claim 14, wherein both the first and second closing arms have inner surfaces that are angled with respect to the directions in which the slide closure body moves along the touch fastener strips, the convergence of the inner surfaces of the first and second closing arms thus gradually compressing and engaging the complementary touch fasteners as the slide closure moves in the first direction along the touch fastener strips. 16. The slide closure of claim 14, wherein each of the first and second closing arms has a width substantially the same as a width of the spanning member, and wherein each of the first and second closing arms attaches on a fixed side to the spanning member and is cantilevered across the width of the spanning member so that its inner surface partly defines one of the channels. 17. The slide closure of claim 16, further including: a first side wall attached to a first side of the spanning member, the first side wall also being attached to the fixed side of the first closing arm; and a second side wall attached to a second side of the spanning member, the second side wall also being attached to the fixed side of the second closing arm, wherein the slide closure thus generally defines a Z-shape from the first closing arm through the first side wall across the spanning member through the second side wall and through the second closing arm. 18. The slide closure of claim 14, wherein the first and second closing arms are formed separately from each other and from the spanning member, the slide closure including at least one spring biasing the first and second closing arms toward one another so that the nip gap is minimized. 19. The slide closure of claim 18, wherein the first and second closing arms are each fixedly connected to a side wall at one side, wherein the closing arms extend generally parallel to one another with the side walls disposed on opposite sides of the slide closure, each side wall extending toward the opposite closing arm, and wherein portions of both side walls are aligned and each includes a hinge in which one side of the spanning member pivots, the spring being arranged to pivot the closing arms about the spanning member so that the nip gap is minimized. 20. The slide closure of claim 14, wherein the touch fastener strips are provided with raised features, and the slide closure includes structure for interfering with the raised features and channeling the touch fastener strips therethrough. 21. The slide closure of claim 14, wherein the spanning member is aligned with the nip so as to also be aligned between the two touch fastener strips. 22. The slide closure of claim 21, wherein the spanning member has a first separating surface, a second separating surface, and a nose in between the two separating surfaces, the separating surfaces diverging apart from one another starting at the nose, the nose pointing toward the nip and the spanning member being adapted to cleave and separate the engaged touch fasteners when the slide closure body is moved in the opposite direction along the overlapping touch fastener strips. 23. The slide closure of claim 14, wherein the slide closure body is configured to move in the opposite direction along the overlapping substrate edges and bring the edges together such that the complementary touch fasteners engage. llel to the axes Xg, Yg, Zg. 5. A long-term navigation device using an inertial master box mounted on a carrier to measure its movements with respect to a frame of reference of fixed directions along three axes Xg, Yg, Zg, comprising: a first motor provided for causing a gimbals to pivot on a first axle secured to the carrier; a second motor provided for causing the inertial master box to pivot on a second axle perpendicular to the first axle and secured to the gimbals; a processor provided for calculating three angles of attitude by running a first inertial-navigation program of strapdown type and for controlling the first and second motors by running a second program which, using the calculated attitude angles, places the inertial master box in a succession of stable angular positions with respect to the said frame of reference of fixed directions, in a sequence of cycles of eight turnings-over of the inertial master box in at least two perpendicular planes, each of constant orientation in the frame of reference of fixed directions. 6. The long-term navigation device according to claim 5, wherein the program executes one turning-over in a first plane, followed by one turning-over in a second plane, followed by two turnings-over in the first plane, followed by one turning-over in the second plane, followed by one turning over in the first plane, followed by two turnings-over in the second plane. 7. The long-term navigation device according to claim 5, comprising a third motor provided for causing the inertial master box to pivot about a third axle perpendicular to the first and to the second axles under the control of the processor and wherein the program makes turning the motors in such a way as to keep the inertial master box in a fixed plane of the frame of reference of fixed directions Xg, Yg, Zg for each stable position of the inertial master box.
